Although the 24" Light Duty Clamp Rack has "light duty" in its name, it's not a light weight when it comes to keeping your clamps organized and well supported. Even if you hang 100 lbs of clamps on it, this rack won't budge. The rack is precision formed from sheet steel and powder coated for years of rust free quality appearance. There are 23 slots to hold many "F" style bar clamps with bars up to 1/4" wide. It also features four mounting holes on 16" centers to easily match up with typical wall stud spacing.
