Clamping large or odd shapes with straps is not a new idea; however, most strap clamps exert force (pull) in only one direction. Strap clamps like this can easily distort/skew the work piece. BESSEY's VAS-23 is different, it pulls equally on both ends of the strap, eliminating the chance of skewing your work piece to one side. The high tensile woven polyester strap is extremely strong & there is a built in take up reel that neatly stores the excess strap to eliminating a potential tripping hazard. Complete with the high quality 2K handle for comfort resulting in a better grip. BESSEY. Simply better.
