This floor mounted fleshing beam mount is the strongest, sturdiest mount on the market. It also has the lowest profile with less than 1" for those trappers with space issues. The fleshing beam bracket comes pre-drilled to fit any beam width 5" and up. Beam slides in and out with a few quick turns of a handle for quick clean up and storage of your fleshing beam. Each mount comes with 4 - 5/16" x 2 1/2" carriage bolts with washers to mount your beam. This mounting system is the last one you will ever buy.
