Mini Trunking is common in the electrical industry for safe cable management. The base is fitted, cables and wires laid within, and a lid clipped into place to complete the rectangle. The lid removes for routine maintenance.
Trunking is self adhesive or plain, in standard sizes of 16, 25 and 38mm wide. For discreet, near invisible cosmetic requirements there is Micro Trunking, suitable for single cables or thin wires.
