Gardner Bender MSI-50B Staple with Polyethylene Strap, 1/2 in W Crown, Steel, Graphite Blue

Insulated metal staples secure a large variety of cable types including NM, BX, MC, AC and UF cables. These staples offer a durable polyethylene insulating sheath to prevent arc faults if the staple is over-driven through a cable jacket. Strong steel constructed staples offer sharp, burr-free tips which easily bite into wood upon hammering and deter wood from splitting. Do not drive the staple beyond the insulation stops to achieve a clean insertion and secure wiring without damage to cable or wood. 1/2 in staples secure two conductor #12 and #14 non-metallic BX, MC, AC and UF cable.
