Klein Tools 45001 Heavy-Duty Cable Stapler for Romex & Data Cables

Reliable, one-handed cable stapling for professional installations

The Klein Tools 45001 Heavy-Duty Cable Stapler is purpose-built to drive insulated staples for loose cable runs with a smooth, controlled motion. Its forward-action handle lets you push the tool rather than squeeze, which can reduce hand fatigue and create a steadier, more comfortable stapling experience. A cable guide runs along the bottom surface to shield cables from incidental piercing or crushing as you work. Staples release from the front of the tool, close to where your hand presses, enabling a natural, intuitive action that supports consistent placement on each pass. Use exclusively with Klein insulated staples for optimal performance.
