Big Fist Magne-Clamp and Bolta-Clamp Tool Mounting System

Mount tools or other large objects to any metal surface and keep items secure and organized…useful in on and off-road vehicles, barns and workshops, and around the home!

If you’re tired of trying to find a good place to store tools on your truck, tractor, ATV or UTV, and especially if you don’t want to drill holes in your machine, you need the Big Fist Magne-Clamp.  The Big Fist Magne-Clamp is an industrial-strength rubber hook with a strong magnet attached to mount to any metal surface.  Big Fist Magne-Clamps are great for safely mounting fire extinguishers, fuel bottles and other cylindrical tools, secure and out of the way. They’re constructed of heavy duty transportation-grade rubber, are not affected by hot or cold temperatures, and are UV resistant, so they don’t degrade when stored outside.

For the ultimate convenience, order the Big Fist Magne-Clamp with its 3-1/4″ diameter 95# pull strength magnet, but for the budget minded, we also offer the Big Fist Bolta-Clamp, which is the hangar with a hole for a 1/4″ (6mm) bolt or screw, to mount in a permanent location (bolt not included).

Either way you order, you’ll receive a mounting clamp that can support a working load of up to 50 lbs.  The grip size of the clamps means they can fit around any object that is between 2 3/4″ and 3 1/4″ in diameter.  Big Fist Magne-Clamps and Bolta-Clamps are also great for workshops, tool trailers, horse barns and vehicles.  So, have the tool you need at your fingertips, when you need it with the Big First Magne- and Bolta-Clamp!
