Trough and ladder cable trays both support cable runs, but they differ in load capacity, support span, ventilation and cable protection. This guide compares the two side by side and explains how to choose by cable type, span, environment and budget, helping EPC contractors, electrical contractors and procurement teams specify the right tray for power, control and data cable installations.

Cover plates, splice plates, bonding jumpers and barrier strips are what turn a run of open cable tray into a complete, protected, code-compliant system — yet they're often specified as an afterthought once the main tray is ordered. This guide covers each accessory category, its role in the system, and the key specification checks (finish matching, bonding continuity, code-required separation) that prevent common field issues like exposed cables, loose splices and failed grounding continuity. It's aimed at EPC contractors and procurement teams building a complete cable tray bill of materials.

Conduit fittings and accessories — elbows, couplings, clamps, straps, hook nails, standoff brackets and electrical boxes — are what turn a length of conduit into a complete, code-compliant electrical system, yet they're often an afterthought once the conduit itself is chosen. This guide covers each fitting category, its role in the system, and the key specification checks (trade size matching, finish consistency, code-required support spacing) that prevent common field issues and failed inspections. It's aimed at EPC contractors and procurement teams building a complete conduit system bill of materials rather than just sourcing the pipe.
