EZ502 end cover is used for 37mm beam extrusion with 1 system groove, Z311. It is made of plastic and weighs 0.006 kilograms, T-shaped. It has a rectangle shape feet which can insert into the beam extrusion perfectly. Generally, it is often installed to the top of the beam extrusion to cover the cross section for better appearance.

If you have the demand, Lingtong will provide the end cover separately or attach the cover to the extrusion and send them to you together.
