Nsi Industries fst100i Insulated Cable Staple 250 Pack

Product Description

The NSI INDUSTRIES fst100i is an insulated cable staple designed to secure low-voltage and power wiring along framing, joists, and other structural surfaces. Measuring 1-1/4 inches in length and 9/16 inches in width, these blue-coded staples provide a reliable mechanical anchor while keeping insulation intact between the staple and the conductor. Each pack contains 250 staples, making it well suited for rough-in wiring work where repetitive fastening is required. Electricians and low-voltage installers use these staples for neat, code-compliant wire routing on residential and light commercial jobs.

These insulated staples are intended for securing electrical cables and conductors to wood framing, blocking, and similar substrates. The blue color coding helps tradespeople identify staple size quickly when working with multiple staple sizes on the same job. The 250-piece pack count supports efficient production wiring on new construction or retrofit installations where cable runs require frequent anchoring at intervals consistent with NEC requirements.

Key Features

• Insulated design protects conductor insulation from staple contact and mechanical damage
• 1-1/4 inch length provides solid penetration into wood framing and blocking
• 9/16 inch width accommodates standard cable diameters

Installation Notes

Installation is performed by licensed electricians or low-voltage technicians using a compatible staple gun or hammer tacker. De-energize all circuits in the work area before fastening cables near existing wiring. Drive staples snug against the cable without crushing the conductor insulation. Follow NEC Article 334 or the applicable code section for required stapling intervals along cable runs.
