Certiflat FabVee - V-Blocks are sold as a complete set containing 2 V-Blocks of each size. These V-Blocks are built from a simple sheet metal design and laser cut to exact dimensions.
The FabVee was designed to be used in welding and fabrication applications, and while we certainly wouldn't call them disposable, they are built and priced in a way that allows peace of mind should they accidentally take abuse from the welder during use.
