Why Cable Tray Master
A manufacturer you can buy direct from, and audit
Cable Tray Master is a cable tray manufacturer and exporter under one owner. We make the tray on our own line in China and ship it with our own export team, so the price is factory-direct, the specification is made to order, and buyers are welcome to visit and audit the plant.
The American device-box family
The common 4" square box, single- and double-gang device boxes and their covers, in the pattern US-standard switches, sockets and devices are built to fit, with knockouts placed for conduit entry.
Steel that takes the run
Pressed and welded steel, pre-galvanized or painted, so the box stands up to the conduit and cabling terminating into it in commercial and industrial fit-out.
One contact for boxes and conduit
Supplied alongside the conduit and cable tray, so the boxes that terminate a run come from the same supplier as the run itself.
What the CTM-BX-US is, and who it is for
American standard steel boxes are the pressed and welded metal boxes that house switches, sockets and cable joints and terminate conduit on US-pattern installations. The family centres on the familiar 4" square box, used as an outlet, junction and pull box, together with single- and double-gang device boxes for switches and receptacles. Knockouts around the box let the installer open just the conduit entries the job needs.
We supply the boxes in the common patterns and depths, pre-galvanized or painted, with the covers and mounting features to suit, and alongside the conduit and cable tray they connect to. Box pattern, depth, knockout layout, finish and any product-specific certification are confirmed with you per order and per destination market.
