ZINC DIE-CAST CONSTRUCTION WITH INSULATED THROAT: Manufactured from heavy-duty zinc die-cast metal with an insulated throat for conductor protection. Resists corrosion, mechanical wear, and impact for long-lasting performance in commercial, industrial, and multi-unit residential electrical installations. Concrete tight when taped for added environmental protection in demanding job-site conditions.

50-PACK BULK SUPPLY FOR CONTRACTOR EFFICIENCY: Includes 50 connectors in 3/8" trade size fitting 1/2" knockouts, cable range 0.405"–0.612". Designed for electrical contractors and procurement teams to reduce supply interruptions, minimize on-site shortages, and support uninterrupted workflow across large-scale commercial, industrial, and multi-unit residential electrical installations and service work.

UNIVERSAL MC, AC, AND HCF CABLE COMPATIBILITY: Supports aluminum and steel armored cable from 14/2 to 10/3 across a cable range of 0.405"–0.612". Fits standard 1/2" knockouts on standard and deep metal electrical boxes and enclosures — reducing SKU complexity and providing a single connector solution across diverse commercial and industrial wiring specifications and applications.

TOOL-FREE SNAP-IN INSTALLATION VIA SPRING STEEL CLIP: External spring steel clip mechanism snaps securely into 1/2" knockout — no screws or specialty tools required. Reduces per-unit installation time for improved labor efficiency on commercial builds, multi-unit projects, and scheduled service work. Ensure knockout edges are clean and burr-free prior to installation for optimal seating and performance.

REUSABLE ONE-PIECE DESIGN FOR LONG-TERM SERVICEABILITY: Solid one-piece zinc die-cast construction delivers structural integrity and extended service life. Removable with standard hand tools during inspections, retrofits, or facility modifications — supporting lifecycle cost efficiency and reducing material waste in ongoing MRO procurement and commercial facilities maintenance programs.
