This product operates as a base rail of the Multi-Rail RL system.
This type of “twin” rail is built from two separate pieces.
When bolted on a base: for example 50×50 M12 grid pattern plate, these form a rail which is 25 mm in height. So the installation of the base differs from Multi-Rail RM installation.
In this base rail the installation bolts are included.
Please note: Multi-Rail RM stoppers, clamps and riser blocks are compatible with the RL base rail.
