Steel Solid Enclosed Cable Raceway with Knock‑outs and Bolt‑Locking System

Steel solid enclosed cable raceway equipped with knock‑outs and bolt‑locking system.

Winwin Group steel solid enclosed cable trunking is a heavy‑duty fully‑enclosed cable management solution designed to deliver complete mechanical protection for power, control and communication cables. Built with robust steel body and removable solid cover, this enclosed cable trunking shields internal wiring from dust, moisture, physical impact and electromagnetic interference, compared with open‑type cable tray systems. Pre‑galvanized, ZAM, Powder coated, hot‑dip galvanized and stainless‑steel finishes are available to satisfy different indoor and outdoor site requirements.

This enclosed steel cable trunking comes with pre‑formed knock‑outs for convenient cable tapping and branch connection on‑site. The reliable bolt‑locking system firmly fastens the cover onto the trunking body, preventing accidental opening during operation and installation. Modular design allows quick assembly with matching elbows, tees, couplings and mounting brackets, greatly cutting down field installation time. All dimensional tolerances are strictly controlled to ensure consistent fitting between straight sections and accessories

Widely adopted for MEP projects, industrial plants, commercial buildings, data centres and coastal facilities, our solid enclosed cable trunking complies with international cable containment standards. As a professional cable tray and trunking manufacturer from China, we support standard sizes as well as custom dimensions for project‑specific demands. Complete sets of matching fittings can be supplied together for one‑stop cable containment system procurement.
