H.S.offer a wide range of components of perforated cable trays. Angle bar bracket is one of the components.These perforated cable trays are offered generally fabricated in mild steel. A big advantage of using strut channel in construction applications is the multitude of options available for quickly and easily connecting lengths together and other items to the strut channel, using various strut-specific fasteners. Channel can be assembled quickly with minimal tools and inexpensive labor, which reduces costs significantly in many applications. A strut channel installation can be modified or added-to easily if necessary. The expensive alternative to strut channel for many applications is custom fabrication using steel bar stock that require welding and/or extensive drilling and bolting. The inwards-facing lips on the open side of strut channel are used to mount channel nuts, braces, connecting angles, and other types of fittings to join lengths of strut channel together or to connect pipes, wire, cable tray, ladder type cable tray, cable trunking, threaded rod etc.
