Doing some electrical work and need to secure your NM cable (like Romex) safely? These GB Electrical insulated staples are the standard. They're designed to hold #14 or #12 gauge non-metallic sheathed cable (BX, MC, AC, UF) snugly against wood joists and studs. The saddle (the part that touches the cable) is made from smooth, UV-resistant polyethylene that won't cut into the wire insulation or rust over time. The two nails are zinc-plated to resist corrosion and are designed to be driven in together with a hammer without splitting the wood. The nail heads are recessed so they don't stick out and snag on anything. They're RoHS compliant and make for a clean, secure, and code-friendly installation. A must-have for any electrician's pouch or DIYer's toolbox.
