Ladder Type Cable Tray-
Is the CL cable tray a trough type or a ladder type
Commonly known as: trough, ventilated cable tray. Cable tray is used for project planning: It is much easier to lay new cables onto a tray system as the needs of a project changes over time, rather than have to pull them through a prior installed length of conduit pipe. A cable ladder, also known as a ladder cable tray, is a support system that consists of two longitudinal side rails connected by individual rungs. These rungs are spaced at regular intervals and provide a structure that resembles a ladder—hence the name. A cable ladder has a range of straight lengths and different shaped fittings designed to facilitate changing cabling directions or levels easily, without the need to modify any components. They provide a secure pathway, allowing easy cable installation, maintenance, and future expansions.
