This linear motion kit is used with the REV 15mm Extrusion System. This kit can be configured in many different ways, but the most common allows for teams to build simple elevators and lifts for their robots. When building light duty lifts, the kit has enough parts for 4 single extrusion stages. When building heavy duty lifts (dual post) the kit has enough parts for 1 complete stage.
NOTE: AS OF 9/21/2016 We have changed the hardware assortment so that these kits are easier to assemble and use. All kits purchased from REV after this date should be the new kits, but old kits may still be available from our wholesalers. If you recieve an old kit purchased after 9/21/2016 please contact us and we will ship you new hardware.
