Streamline your rough-in electrical work with the industry-trusted reliability of the nVent GARDNER BENDER MSI-175BX Insulated Metal Staples. Proudly Made in the USA, these 9/16 in. wide staples are specifically engineered to offer structural strength, advanced cable protection, and rapid installation for residential and commercial framing and construction applications. Designed for optimal versatility, these insulated staples are ideal for securing and protecting three-conductor #14, #12, and #10 Non-Metallic (NM) cables, as well as BX, MC, AC, and UF jacketed wiring. Each staple features a durable polyethylene insulator strap that creates a protective barrier between the steel and the wire jacket. This unique design safeguards your cables from over-driving, prevents insulation damage, and actively helps prevent arc faults to ensure long-term electrical safety. Crafted from premium-grade steel, the robust construction provides the rigid strength necessary to hold heavy cable runs without bending. Installers will appreciate the sharp, burr-free tips that ensure easy starting with a standard hammer. The clean, pointed ends bite effortlessly into wood studs and joists, maximizing driving efficiency while drastically reducing the risk of splitting the wood framing. Whether you are a professional electrician wire-mapping a new home or a dedicated DIYer upgrading household circuits, these premium staples deliver code-compliant security. To install, simply place the staple squarely over the centered cable and drive it into the wood using a hammer until it meets the integrated insulation stops. Do not drive the staple beyond the insulation stops to achieve a clean insertion and secured wiring without damage to cable or wood. Boost your productivity and secure your electrical infrastructure with this convenient, contractor-ready 175-box.
