Expand your work area with our riser block family. Use your imagination and place these five-sided risers vertically or horizontally. Each 5/8” precision hole can be used with our clamps, stops, pliers and other tooling. Mount to the top of our table to create custom jigs for your projects. Join multiple blocks to create beams. Attach tableside to expand horizontally. Made from 1/4 A36 HRPO, these blocks are stout — don’t drop them on your toes!
