The Bora All-Terrain Sawhorse with STABLZ Technology (PM-4250) is designed with imperfect worksite in mind. In a perfect world, the floor of your worksite is flat all the time. But we don’t live in a perfect world — so you need a sawhorse built for uneven ground. Bora created the PM-4520 All-Terrain Sawhorse with STABLZ technology to be the only sawhorse that adjusts to irregular or rough terrain with just a simple tap, eliminating wobbles in seconds.
