DAVIS Quick Fist User Manual

If you plan on holding a large cylinder with the base

unsupported, it is advisable to use a piece of angle

iron, wood block or shelf bracket at the bottom of the

cylinder. This will prevent slippage (especially on a

vehicle) and will also make it easier to lock the clamp

in place.

INSTRUCTIONS

See separate document for standard size Quick Fist (#540) instructions.

Super Quick Fist®is a one-piece rubber clamp that mounts

easily to keep equipment firmly in place. Ideal for holding

fire extinguishers, oxygen cylinders, CO2tanks, and other

equipment. Use on boats, off-road trucks, military equip-

ment, ATVs or any vehicle. Can also be installed in struc-

tures such as storage sheds.

Quick Fist clamps are made of heavy duty transportation

grade rubber. They’re UV resistant and withstand

extreme heat or cold. Ideal for marine use,

since Quick Fist will not rust or corrode.

Mounts easily with three #10 (5 mm) bolts

or screws (not included).

To Install:

Super Quick Fist can be mounted with the strap fac-

ing in any direction. Use three #10 bolts or screws to

fasten. Do not over tighten.

After mounting Super Quick Fist, stretch the strap by

putting one hand on the base and using the other to

pull in a perpendicular direction several times on the

strap.
