Z175A end cover is used for 50mm beam extrusion with 2 system grooves Z400A, Z400B, Z402, Z403, Z460, ZL402. It is made of plastic and weighs 0.004 kilograms. It has four 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. In addition, the cover can avoid injury when people hit the extrusion, for the sharp cross section of the extrusion is covered. 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.
