The electric slide was not built on this unit

The electric slide was not built on this unit, but it should have been! Our 20mm aluminum slide unit is one of our most popular items for those looking to build their own linear system. Our featured slide unit is open, making it perfect for a supported shaft. This block has a pre installed 20mm linear bushing and has 4 threaded mounting holes on top ready for installation. The block, itself, is made of durable aluminum. http://www.vxb.com/page/bearings/PROD/LM/Kit8306
