This is an improvement to the AndyMark 2x1 Elevator System, which is designed to be a robust, simple solution for building reliable linear motion systems. This new version has thicker and stronger plates to prevent bearing tearout, but also includes new hardware that allows for easy-to-build multi stage elevator structures. This easy-to-build kit solves one of the most difficult parts of building these mechanisms by providing precision cut sheet metal brackets to support the rollers and bearings for a smooth single-stage linear system. This kit takes the 2x1 Single Stage HD Elevator Bearing Kit (am-3779a) and combines it with our 2 in.x1"x0.063" Aluminum Box Tubing (am-3214-6) with some hardware to create a lightweight and versatile linear motion system.

Note: This product is specifically designed for 2 in.x1" (outside dimensions) aluminum box tubing. It is not compatible with other sizes of aluminum tubing.
