Built different than conventional style vises, the Palmgrencombination bench and pipe vises houses a super strongpower tunnel with straight-line pull that assures a lifetimespindle and nut never to wear out. A precision fit of the slidebar eliminates side play and jaw wobble even whenclamping with the jaws wide open. The vise spindle and nutare totally enclosed in a square tube casting that protectsthem from dust, chips and moisture, keeping them lubricatedfor life. The body is heavier and made of 65,000 psi ductilealloy stress parts. They're practically indestructible and are70% stronger than the competitive u-shaped styles.Thesevises have the throat depth to meet the toughest jobrequirements and come with both hardened and replaceablesteel serrated jaws and pipe jaws. Reinforced large anvils aredesigned to handle additional non-clamping applications. A360 swivel base with dual lock downs and 4 point mountingholes deliver secure, safe clamping. These vises are ideal formaintenance applications, tool and die shops, fabricationshops, automotive garages, tradesmen and construction sites.These vises can be used in indoor and outdoor applications.65,000 PSI ductile castingsSealed constructionStraight line pull power tunnel designPrecision fit slide bar to 0.003"Replaceable serrated steel jawsReplaceable pipe jawsLarge anvil360 swivel base with dual lock downsLIFETIME WARRANTYThe 9629494 and 9629496 have a patented quick adjustingfunction that allows for rapid opening, closing and positioning of the jaws to the workpiece for faster, cost saving clamping.
