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.

Wire mesh and perforated cable tray are both open support structures for cable runs, but their construction differs fundamentally: wire mesh is a welded open grid that can be cut and reshaped on site with basic tools, while perforated tray is a solid sheet with punched holes offering continuous base support. This guide compares the two by installation flexibility, cable support and typical applications, helping specifiers choose wire mesh for data/IT cabling and retrofit projects versus perforated tray for industrial power distribution and heavier cable loads.
