Cable Staples for NM and Coaxial Cable

Gardner Bender MPS-2125 staples secure 10/2 NM, 12/3 NM, 16/4 speaker wire, RG-6 coaxial and CAT5e cables to wood surfaces. The 1/2 in. plastic saddle prevents insulation damage while the steel legs hold firmly. Electricians and low-voltage installers use them for residential wiring and structured cabling runs. They are not suited for conduit systems or metallic-sheathed cables that require insulated clamps.

Rust-Resistant Steel and Plastic Construction

The staples combine a black plastic saddle with plain-finish steel legs for corrosion resistance in dry indoor locations. No moving parts or power draw are involved, so thermal output and acoustic noise are non-existent during normal installation. The materials remain stable across typical attic and wall-cavity temperature ranges without degradation.

Sustained Holding Under Structural Load

Once driven, the staples maintain continuous clamping force on the cable jacket without relaxation over time. The steel legs resist withdrawal from wood framing under normal building vibration and thermal cycling. They are not designed for repeated removal or re-use, and they do not accommodate cable bundles that exceed the 1/2 in. saddle capacity.

Questions about this item

How do I install the 1/2 in. Cable Boss staples without crushing 12/3 NM cable?

Use a compatible staple gun, position the plastic saddle over the cable, and drive the steel legs into wood until the saddle sits flush — do not over-drive or the saddle can pinch the conductors.

What part of the MPS-2125 staples will need replacement first on an outdoor run?

The plain-finish steel legs will rust before the black plastic saddle degrades; once corrosion appears, remove and re-staple with fresh staples to maintain holding power.

At what cable size does the 1/2 in. staple leg length stop providing enough grip in framing lumber?

The 1/2 in. leg length is sized for cables up to 10/2 NM; larger bundles such as 10/3 or 8/2 NM reduce penetration depth and holding strength in wood.
