Introduction
Thank you for purchasing the ClearSpanTM Greenhouse Bench. We appreciate your patronage. We
hope you enjoy building and utilizing your bench. Please read this entire instruction manual before
starting to assemble your bench. If you require assistance during the construction process you may
call us at 1-888-603-4445.
A Word About Safety
Just as we want you to be pleased with your assembled bench, we donʼt want you to get hurt in the
process of building it! Our suggestions include the following:
• Wear eye protection when drilling and power-screwing.
• Wear head protection when working with/under heavy parts including metal tubing.
• Wear gloves when handling metal parts due to sharp or rough edges.
• Use a portable GFCI when working with corded power tools.
• Do not climb on the bench or its frame. It is not designed to support human weight.
• If bench is moved after construction, inspect bench thoroughly before reuse.
• Use common sense at all times.
Required Tools
Before you start to build your bench you should assemble the following tools:
• Tape Measure at least as long as your bench
• Fine Point Marker to mark locations during assembly
• Electric Drill/Driver (cordless preferred)
• 5/16" Hex Driver Bit
Unpack & Identify Parts
Before you begin to assemble your bench you should first unpack the contents of your
shipment. During this process you will both verify that you have all the parts required to build your
bench and learn what all of the various parts look like.

(2) Short extruded aluminum end rails with mitered ends (2', 4', or 6' long depending on model)
(4) Steel legs with attached feet
(4) Galvanized steel tubing cross supports
(4) Galvanized steel split “T” clamps (2 halves with nut and bolt)

Bench Assembly
Step 1: Install a 5/16" hex driver bit into the chuck of your drill/driver.
Step 2: Attach (2) short side rails to (1) long end rail to form a U-shaped assembly. Use (1) corner
splice and (2) Tek screws in each corner. Be sure to line up the channels grooves before
inserting the Tek screws. Use a mallet if necessary to tap the splices into the channel grooves.

Step 3: Lay your U-shaped frame assembly up side down on the ground as follows:
• With the small groove DOWN if using an expanded metal top
• With the small groove UP if using a plywood, polymax sheet, or other top material
Step 4: Slide (2) band clamps onto each cross support tube
Step 5: Slide the first cross support tube into the channel in the side rails of your frame. Position it
so the centerline of the tube is 12-1/2" from the end rail.
Step 6: Install remaining cross supports spaced 24" on center from each other.
Step 7: After checking the positions of your cross supports, secure them in place with a single Tek
screw at each end through the channel into the cross support tube.
Step 8: Slide (2) band clamps onto each leg tube.
Step 9: Attach (2) legs to both of the outermost cross supports using a split “T” clamp for each leg.
Position the legs from the side rails using the distances given in the table below:
Width of Table Model Leg Inset from Side
2' 1"
4' 9"
6' 12"

Step 10: Attach an untwisted end brace from each leg to the cross support the leg is attached to.
The braces are attached using the band clamps previously installed.
Step 11: Attach a twisted side brace from each leg to the neighboring cross support. The braces are
attached using the band clamps previously installed.
Step 12: Check that all (4) legs are straight and plumb. Adjust braces if necessary and retighten.

Step 13: Flip your assembly right side up so the feet are now on the ground.
Step 14: If you are NOT installing the optional expanded metal top, add the remaining end rail to
your frame using a pair of corner splices and Tek screws. If you are installing the optional
expanded metal top, skip this step as it will be performed after the top in inserted.
Step 15: Attach your top material to the frame. If you purchased the optional expanded metal top,
follow these additional sub-steps:
• Spray the narrow channel of your frame with lubricant (silicone. WD40, etc.)
• (3) workers should put on gloves to protect their hands from sharp edges
• Insert the narrow end of the top into the small groove in the frameʼs open end
• Position one worker at each side of the frame
• Position a third worker at the roll of expanded metal top material to hold it up and feed it.
• Workers 1 and 2 pull the top down through the frame while worker 3 supports the material.
• Add the remaining end rail to your frame using a pair of corner splices and Tek screws.
