Ecm Industries Llc PR-50 Nm Cable Staple 7/16 in 50 Pack

Product Description

The ECM INDUSTRIES LLC PR-50 is a 7/16-inch round non-metallic cable staple designed to secure NM electrical cable to wood framing and structural members. Sold in bags of 50, these staples feature a smooth saddle profile that holds wire firmly in place without cutting into the cable jacket or damaging insulation. The PR-50 is a standard fastening component used during rough-in electrical work in residential and light commercial construction. Its non-metallic body is appropriate for use with non-metallic sheathed cable runs where a clean, low-profile fastener is required.

The PR-50 is suited for securing 12/3 and 14/3 NM cable in residential wiring applications. Electricians and rough-in crews use these staples when running branch circuit wiring through studs, joists, and plates. The 7/16-inch round opening accommodates the typical outer diameter of common residential cable sizes, making these staples a practical choice for general wiring runs throughout a structure. The 50-count bag format supports efficient staging on the job site.

Installation Notes

Installation is typically performed by licensed electricians during the rough-in phase of electrical construction. NM cable stapling must comply with NEC requirements for support spacing and proximity to boxes and fittings. Drive staples flush without crushing or deforming the cable jacket, as over-driven fasteners can damage insulation and create a code violation. Always confirm power is off and circuits are de-energized before securing or repositioning any wiring.
