SELECTING THE RIGHT EQUIPMENT
Whatever your application, selecting the proper equipment for the job is very important. Proper selection along with regular inspection
and maintenance will help keep operating costs minimal while providing long life to each component. Below are general guidelines for
selecting Premier Coupling and Drawbar Eyes. If you feel that your application is unique, please give Premier a call so that we may help
you through the selection process.
Follow these four steps to ensure proper selection of Premier Couplings and Drawbar Eyes.

For “Double Trailer” configurations, only the rear trailer is considered when selecting
your Premier Coupling or Drawbar Eye. In this example, a Coupling and Drawbar Eye with
a “Gross Trailer Weight” rating of 40,000 lbs. (18,143 kg) would be the minimum rating
acceptable for normal, over-the-road applications (see Tongue Weight section below).
For “Triple Trailers”, only the two most rearward trailers are considered in selecting
your Premier Coupling or Drawbar Eye. In this example, a Coupling and Drawbar Eye
with a “Gross Trailer Weight” rating of 80,000 lbs (36,287 kg) would be the minimum
acceptable for normal, over-the-road applications. (See Tongue Weight section below).
STEP 1:
Determine “Gross
Trailer(s) Weight”
(GVWR(s) of towed trailers)
STEP 2:
Determine “Tongue
Weight Capacity”
(Maximum occurring
tongue weight)
STEP 3:
Add Margin of Safety
(Dependent upon your
equipment and operating
environment)
STEP 4:
Browse Premier
Product Catalog
(Based on Steps 1-3)
STEP 1: Determine “Gross Trailer(s) Weight”
“Gross Trailer(s) Weight” is usually determined by the Gross Vehicle Weight Rating (GVWR). This information is attached to the trailer by
the trailer manufacturer.
STEP 3: Consider Operating Conditions and Environments
Environments such as rough uneven roads or off-road use can dramatically increase shock loads to both drawbar eyes and couplings. In
general, increasing the “Gross Trailer Weight” (Step 1:) and “Tongue Weight Capacity” (Step 2:) by a minimum of 25% will be sufficient
for many applications. Even if an application is used off-road occasionally, the minimum increase necessary for Gross Trailer and Tongue
Weight is 25%. Certain types of equipment and/or operating practices can also dramatically increase loads through equipment binding
and/or improper loading practices. Of special concern is high tongue weight. However, each application is unique and every environment
different, therefore your application may require more than 25%.
Once both “Gross Trailers(s) Weight” (Step 1:) and “Tongue Weight Capacity” (Step 2:) have been determined, evaluate your operating
conditions and apply an appropriate margin of safety.
STEP 4: Browse Premier Product Catalog
Browse the Premier Product Catalog and refer to the “Specifications” section of each product. Be sure to review the “Understanding
Premier Load Specifications” sections and “Coupling to Drawbar Eye Cross-Reference” sheet on the next couple of pages.
STEP 2: Determine “Tongue Weight Capacity”
“Tongue Weight Capacity” is the maximum expected weight at the drawbar eye.
If a hinged drawbar is used, the maximum weight will be approximately 1/2 the
overall drawbar weight. If a non-hinged drawbar is used and the actual tongue
weight is not known, you can approximate the weight by multiplying the GVWR
of the towed trailer by 15%. However, each application is unique and the best
practice is to weigh the tongue when the trailer is loaded to GVWR.

Understanding Premier Load Specifications
Each Premier product undergoes extensive design and testing prior to being introduced. We use the latest in Computer Aided Design and
Analysis Software as well as physical destructive tests. Premier’s published load specifications are the maximum load a given product or
part will withstand without failure. Premier’s testing procedures closely follow the Society of Automotive Engineers (SAE) guidelines of
Recommended Practice for testing Couplings and Drawbar Eyes (SAE J847 & J849).
SELECTING THE RIGHT EQUIPMENT

Importance of Inspection and Maintenance
Whether you use Premier Jacks, Couplings, Drawbar Eyes, Hinge Assemblies or any other Premier product, regular inspection and
maintenance are essential for proper function, keeping repair costs to a minimum and above all, safe and efficient operation.
To determine wear limits, Premier created Wear Gages that help judge the useful life of couplings and
drawbar eyes (details in catalog). In accordance with Premier and the Federal Motor Carrier Safety
Regulations, these were designed to identify wear at the critical percentages of 18% and 20%, by
measuring the cross-section of coupling hooks (horn) and drawbar eye loops. 18% wear indicates that
the product should be replaced as soon as possible. At 20% wear, the product is no longer in usable
condition and must be taken out of service immediately and replaced. The latch gage bar measures the
gap space between the top of the coupling hook and the closed latch. If the 3/8” latch gage bar can
pass between this region, then the latch components should be considered worn past safe limits and replaced. Please note that these wear
gage specifications are in accordance with Premier Mfg. and the Federal Motor Carrier Safety Regulations (refer to other manufacturer’s
specifications for wear limits on their products).

MODEL 1200 COUPLING
Installation
The 1200 Coupling is only to be used and maintained with Premier parts listed in the Replacement Part Information section. Any
substitution or use of non-Premier parts in a 1200 Coupling will VOID ALL PRODUCT WARRANTY.
Installation Procedure
1. The 1200 Coupling must be installed to comply with the Federal Motor Carrier Safety Regulations. Specifically, Section
393.70, Paragraph C: “Towing of Full Trailers.” Prior to install or operation, consult with local, State and Federal agencies, as
there may be additional applicable laws governing installation and use of this product.
2. Make certain that the cross member the 1200 Coupling is to be mounted on is of sufficient strength to withstand the load rating
of the coupling.
3. If using the 1200 Coupling with a 281 Air Chamber, a 267 Air Chamber Bracket and a 271 Thimble, measure the mounting
structure thickness and cut the pushrod on the air chamber to a length of 3 5/8” plus the mounting structure thickness (i.e.
1/2” thick mounting structure would equate to: 3 5/8” + 1/2” = 4 1/8” pushrod).
4. Using the Standard Installation Drawing, measure and layout the cross member and then drill the holes for the mounting bolts
and pushrod.
5. Mount the 1200 Coupling using either Premier’s 501 Bolt Kit and provided torque value, or four other 3/4” grade-8 bolts and
grade-C locknuts. Only use new fasteners when mounting couplings or drawbar eyes and torque to SAE specifications. If using
the 1200 Coupling with a 281 Air Chamber, mount the chamber, 267 Air Chamber Bracket and 271 Thimble as shown in the
Standard Installation Drawing. The two longer (2 3/4”) mounting bolts in the bolt kit are used for mounting the coupling and
air chamber bracket to the cross member. WARNING: Never use an air chamber on a Premier coupling without a 271 series
thimble.
6. Once mounted, check the latch components for proper operation and clearances (see the Inspection/Operation/Maintenance
section for opening and closing the latch). If the operation of the latch components is sticky, lubricate all rotation points with
a light penetrating oil. Work the latch assembly several times to distribute the lubricant evenly and remove any excess with a
rag. Do not apply lubricant to the pintle/hook or saddle area of the 1200 Coupling.
7. Plumb the air line to the 281 Air Chamber from the vehicle’s emergency side air supply. NEVER use the service side air supply.
8. WARNING! Keep hands clear of the 1200 Coupling during this test. Activate the emergency side air supply by releasing the
emergency brake and visually verify that the 279 Shoe fully rotates toward the pintle.
9. If the 279 Shoe does not move, verify that the Air Chamber has been connected to the emergency side air supply and that the
pushrod length is correct.
10. If the 279 Shoe does not move, verify that the 281 Air Chamber has been connected to the emergency side air supply and that
the pushrod length is correct.
11. When the emergency side air supply is removed, the shoe should completely retract. Please note: The 279 Shoe acts as a shock
absorbing device to help smooth the ride between vehicles. It is not considered part of the latching mechanism.
12. “IMPORTANT WARNINGS!” sticker was enclosed. This must be attached to the coupling or cross member and be visible for
the end user to read.
Inspection/Operation/Maintenance
Inspection and Maintenance:
1. Visually inspect the coupling body and latch components for cracks, impact damage and/or deformation before each and every
use. Do NOT use if any of these conditions exist.
2. Check the gap between the 2072 Latch and the top of the pintle/hook on the coupling body before each and every use. A gap
of 3/8” or more means the coupling must be taken out of service and repaired or replaced.
3. If the wear area on the pintle/hook has worn 20% or more from its original cross-section, the coupling is considered out of
service and must not be used.
4. Lubrication of the latch components must be performed at 90-day intervals or sooner depending on the operating environment.
Lubricate the latch components with a spray-type lubricant to evenly coat all rotation points. Rotate each latch component
several times to evenly distribute the lubricant.
5. Remove any excess lubricant with a rag. Do not apply lubricant to the pintle/hook or saddle area of the coupling.
6. Never weld on any Premier part in order to repair damaged or worn areas. Field and/or shop welds are inadequate and may
further weaken the coupling.
7. WARNING: Other inspection and maintenance procedures are also required prior to the operation of combination vehicles.
Consult and follow all Federal Motor Carrier Safety Regulations as well as local, state and federal guidelines.

Page 7 1-800-255-5387 • www.premier-mfg.comPREMIER MANUFACTURING
IMPORTANT GUIDELINES that apply to all Premier Air Adjusted Couplings
- Do not weld on any coupling assembly
- Always use Grade-8 fasteners properly torqued
- Do not apply lubricants to the coupling hook
- Air service chamber must be Type-24 or Type-30 with 90-120 PSI air supply
- Clean & inspect coupling for damage & excessive wear prior to each and every use
- Lubricate all coupling components at a minimum of 90 day intervals
- Do not bind-up (Jackknife) any application as stresses can cause damage to products or components, resulting in failure and
detachment of the trailer while in use
MODEL 1200 COUPLING
Operations
Operation:
OPENING Coupling Latch:
1. While facing the mounted 1200 Coupling, push the 2073 Latch Lock toward the mounting plate (away from you) until full
rotational travel is reached. While holding the latch lock in this position, grasp the top of the 2072 Latch and pull out toward
the pintle, rotating the latch until full rotational travel is reached.
2. Holding the 2072 Latch in place, slowly release the 2073 Latch Lock until it has rotated into the latch.
3. Release the 2072 Latch and the 1200 Coupling is now open and ready to couple or uncouple.
CLOSING Coupling Latch:
4. Rotate the top of the 2072 Latch toward the pintle until full rotational travel is reached and hold in place. Push the 2073 Latch
Lock toward the mounting plate as far as it will go.
5. While holding the 2073 Latch Lock in this position, slowly release the 2072 Latch. Next, release the latch lock making sure it
seats fully down in the slot on top of the latch. The 1200 Coupling is now closed.
6. To test for proper latching, apply a force toward the coupling body to the front of the 2072 Latch (down near the top of the
pintle). THE LATCH SHOULD NOT OPEN! If the latch does not stay closed, do not use until it has been repaired or replaced.
7. This product is designed to be operated within its free rotation limits. It is the responsibility of the vehicle designer/end user
to assure that these limits are not exceeded (do not bind-up/jackknife).
8. WARNING: Prior to towing, make certain that adequately rated safety chains have been properly connected.
