Abrasion-Resistant Extension Cords

NEMA 5-15 Plug

NEMA 5-15 Socket

Thick insulation protects the internal wires of these cords so they can be used in high-traffic areas and over rough surfaces. The industry designation is STW, so the insulation resists water.

Drop-Down Cable

Often used to wire pendant switches, this cable hangs from an overhead connection. It’s also known as bus drop cable.

The PVC insulation resists abrasion, chemicals, and oil.

Cable with strain relief has galvanized steel strain cables on the sides to provide strength and reduce the stress caused by equipment hanging from cable. Use the strain relief hardware (sold separately) to secure equipment to the cable.
