High-quality aluminium linear rail profile with an extremely smooth v groove on all 4 sides. It's precise, easy to work with and allows you unlimited design control through its modular nature. V-Slot Linear Rail is the ultimate solution combining both linear motion and a modular, structural framing system. It's lightweight yet rigid and provides an ultra smooth track for precise motion. In 2013, OpenBuilds created V-Slot Linear Rail and has added a library of compatible modular Parts which today is known as the OpenBuilds System. Over 1,000,000 feet of V-Slot has been shipped to businesses, classrooms, laboratories and makers all over the world! Much like working with lumber, you can cut V-Slot on a chop saw (using a metal blade) or even use a hacksaw. From there, you simply use a screw driver to make the connections.
