The USA made GyroJaw for once and for all solves the difficult problem of firmly clamping angled or tapered work pieces in a bench or mechanic’s vise — and at a very modest cost. The solid steel stud with a rounded surface rests against the vise jaw when you close up, while automatically moving to the position and angle that produces solid direct pressure on the piece being clamped. The 2 x 3-1/4″ mating face uses an indestructible nylon/glass fiber combination with just enough give to make it non-slip. Get Gyrojaw to add pivoting vise face functionality to meet all your tough clamping needs. Clamp what you’ve never been able to clamp before!
