DAVIS Quick Fist (Super) User Manual
Instructions
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.

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.

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

putting one hand on the base and using the other to
pull in a perpendicular direction several times on the
strap.
