Made in America, the 445 Speedbench™ vise plates are 1/4" cold rolled steel.  Powdercoated red, they are laser cut to fit the vise profile of the Yost 445 series and most 4.5 and 5.5 inch vise bolt configurations. (8) mounting holes fits american standard 1/4-20 and (6) are 8mm metric quick disconnect for extruded rail kits . (8) holes are tapped for 3/8 - 18 bolts so you can bolt your vise directly to the plates for flush mounting to allow the vises to slide for adjustment on the rail kits to give you great flexibility for the jaws of multiple vises across our 24" 48" or 60" rail kits.
