The Vevor pipe welding vise is designed to securely clamp pipes from 1/2" to 8" for welding, maintenance, and assembly work. Its dual 43.7" chains and dual crank handles help distribute clamping force evenly for stable holding. Built from heavy-duty cast iron, it is made to withstand heat, strain, and demanding jobsite use. Precision-machined swivel nuts, pins, and chain screws provide reliable, accurate clamping. This vise is suitable for piping, machinery, construction, and other high-intensity pipe work.
