The CAMBRIDGE 110270 is a 1/2 inch plastic staple designed for securing NM (non-metallic sheathed) cable along framing members, joists, and studs during residential wiring installations. These staples are sold in bags of 50 and provide a fast, consistent method for routing and anchoring NM cable without cutting into the jacket. The plastic construction reduces the risk of insulation damage compared to metal fasteners, making them a practical choice for electricians working to NEC requirements for cable support and protection.
These staples are used in residential and light commercial electrical rough-in work where NM cable is the wiring method of choice. Typical applications include new construction framing, panel feed runs, circuit branch wiring, and retrofit cable additions in wood-frame structures. The 1/2 inch size is suited for standard 14/2, 12/2, and similar NM cable profiles commonly run in residential settings. Electricians and electrical contractors are the primary installers of this type of fastener.
Designed as an OEM-style replacement and standard-use fastener compatible with 1/2 inch NM sheathed cable installations in wood-frame residential and light commercial construction.
Installation is performed by licensed electricians following NEC guidelines for cable support spacing and protection. De-energize all circuits in the work area before routing and fastening cable. Drive staples squarely across the cable without crushing the jacket — overtightening can damage conductors. Follow applicable local electrical codes for maximum support spacing along cable runs.
