Connecting devices used in conjunction with the Miller Grip Anchorage Connector must be attached to the anchor loop only.
Miller Grip Model #494 is designed to be used for fall protection applications only. It is not to be used in any other anchoring
situation. Only trained and competent personnel should install and use this equipment. The device may be installed in horizontal,
vertical or overhead/ceiling surfaces. It may also be used in Miller approved horizontal and vertical lifeline systems.
The structure that this product is anchored to must be capable of supporting 5,000 lbs. (22.2 kN) per user attached; or be de-
signed, installed and used, under the supervision of a qualified person, as part of a complete personal fall arrest system which
maintains a safety factor of at least two. Anchorage requirements based on ANSI are as follows:
• For fall arrest systems, anchorages must withstand a static load of 5,000 lbs. (22.2kN) for non-certified anchorages or two times the maxi-
mum arresting force for certified anchorages.
• When more than one personal fall arrest system is attached to an anchorage, the above anchorage strengths must be multiplied by the number of
personal fall arrest systems attached to the anchorage.
The Miller Grip Anchorage Connector is designed for use with Miller approved components. Substitution or replacement with
non-approved component combinations or subsystems or both may affect or interfere with the safe function of each other and
endanger the compatibility within the system. This incompatibility may affect the reliability and safety of the total system.
A safe anchor point is established when the Miller Grip Friction Bolt Anchorage Connector (#494) is inserted into a friction bolt
with an outside diameter of 39mm (1-1/2 in). Follow manufacturer’s instructions for proper installation of friction bolt.
IMPORTANT!
Remove all dirt and debris from inside the friction bolt before placing this unit. Use the friction bolt anchor cleaning
bushing to clean the inner walls and blow the hole out with compressed air prior to inserting the friction bolt.
Installation and Use of Miller Grip Model 494

WARNING!!
x Use the proper method of coupling to anchorage.
x Do not use incompatible connectors with this device. Use only Miller approved connectors/connecting devices, such as auto-
locking snap hooks and carabiners. Always ensure that connectors are fully closed and locked when in use. (Refer to sepa-
rate instructions supplied with the connecting device.)
x Always work directly under the anchor point to avoid a swing-fall injury.
x Always check for obstructions below the work area to make sure potential fall path is clear and allow adequate fall clearance
below the work surface.
x The authorized person/user shall have a rescue plan and the means at hand to implement it when using this equipment.
x Remove unit from service if subjected to fall arrest forces. This product is not designed to be repaired or altered in any way.
x Never use fall protection equipment for purposes other than those for which it was designed.
x Equipment must not be exposed to environmental hazards and chemicals which may produce a harmful effect.
x Do not allow equipment to come in contact with anything that will damage it, including, but not limited to, sharp, abrasive,
rough or high-temperature surfaces, welding, heat sources, electrical hazards, or moving machinery.
x Do not expose the equipment to any hazard which it is not designed to withstand. Consult the manufacturer in cases of doubt.
x Pregnant women and minors must not use this product.
Proper Placement Guidelines
x The friction bolt anchor must be inserted 4” (101.6mm) to 8” (203.2mm).
x Make sure the unit is in a straight section of the friction bolt.
x Place the spoons so they rest on the inner walls of the friction bolt and not on the split section.
x Give a slight tug on the anchor loop to set in place [5-10 lbs (2.3-4.5kg)].
x You must be able to see and have access to the cleaning bushing from outside the friction bolt. Do Not place in a bent sec-
tion of the friction bolt or to where the cleaning bushing is not visible.
x The friction bolt must be embedded into the substrate. Do Not use the anchor in a friction bolt that is sticking out of the
substrate or is in a cavity without the substrate supporting the friction bolt. Friction bolt must be properly installed.
The Miller Grip Friction Bolt Anchor shown
inserted 4” (101.6mm) into the friction bolt.
WARNING: The spoons must not rest
on the split section of the friction bolt.
When placing a Miller Grip Friction Bolt Anchor, place your thumb inside the anchor loop and your first two fingers around the
trigger. Retract the trigger until the spring bottoms out. With your other hand, pinch the two spoons between your thumb and in-
dex finger. IMPORTANT: Hold the trigger fully retracted while inserting the unit into the friction bolt. Both spoons must be evenly
placed side by side at the bottom of the hole. DO NOT force the unit into the hole. Insert the unit slowly and gently.

When using the Miller Grip Friction Bolt Anchor within a Miller approved Temporary Horizontal Lifeline System, the maximum
number of users is two (2) simultaneously. System capacities are based on the maximum user’s weight (including tools, clothing,
etc.) of 400 lbs. (181.4 kg). Miller Fall Protection requires the use of a Miller full-body harness and shock-absorbing lanyard or
self-retracting lifeline/fall limiter that limits fall arrest forces with the horizontal lifeline system. All instructions and warnings pro-
vided with the body wear, connecting device and horizontal lifeline system, must be read and understood before using the equip-
ment.
To meet the requirements set forth in OSHA 1926.502, the Temporary Horizontal Lifeline must be "installed and used as follows:
(i) as part of a complete personal fall arrest system which maintains a minimum safety factor of two; and (ii) under the supervision
of a qualified person." The horizontal lifeline system must include an inline energy absorber that is designed to keep the forces
on each anchorage connector to a maximum of 3,789.5 lbf. (16.9kN). This force requires that the anchorage connectors and the
substrate to which they are attached must be capable of supporting 7,579 lbf. (33.7kN) in the direction of pull. The Miller Grip Fric-
tion Bolt Anchor has been tested and rated for 10,000 lbs. (44kN) to meet OSHA's requirement for the system.

Fitting
If a Miller Grip anchor becomes stuck, insert a
punch, screwdriver or pointed object into the fric-
tion rock bolt until the tip rests on the striker
plate. (The striker plate is the flat end of the
bushing that is exposed when the unit is placed
in the friction bolt and will be easily visible.) Give
a LIGHT, blunt tap with a hammer or heavy object.
