The WL9‐28831 is the Wilton 400S Machinist 4 inch Jaw Round Channel Vise with Swivel Base, engineered for the most demanding clamping applications. Built in the USA, this vise features a rear‐mounted vise nut that delivers straight‐line pull and even pressure, increasing durability and stability under load. Its round‐channel design encloses the spindle and nut assembly, protecting internal components from debris while maintaining smooth, consistent operation. Constructed from massive cast iron that weighs significantly more than competing models, the 400S provides exceptional rigidity and long‐term performance. Hardened, serrated steel jaw inserts ensure a secure grip, while the large machined anvil surface and double‐lockdown 360 degree swivel base offer versatility for metalworking, fabrication, repair, and shop environments.
