Built on the MacPro 5-knuckle platform, it features a QC8 Quick Connect 8-wire harness that routes low-voltage wiring through the hinge barrel, eliminating exposed wire loops at the door frame. The steel base construction provides standard-weight load capacity, and the BSP Black Suede Powder Coat finish offers a durable, matte appearance suited to commercial interior door installations. Sized at 4.5 inches x 4.5 inches, this hinge fits standard commercial door preps.\u003c\/p\u003e\u003cp\u003eThis hinge is specified for commercial and institutional projects where electrified door hardware is required — card access, electric strikes, magnetic locks, or door position monitoring. The 8-wire QC8 quick connect configuration supports multi-conductor low-voltage circuits common in access control and security integrations. It is a full mortise design, meaning both the door and frame leaves are recessed into routed pockets, making it appropriate for hollow metal or solid wood commercial door assemblies installed by finish hardware contractors or commercial door and frame crews.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQC8 Quick Connect 8-wire electrified barrel routes low-voltage wiring cleanly through the hinge\u003c\/li\u003e\n\u003cli\u003e5-knuckle MacPro full mortise configuration for standard commercial door applications\u003c\/li\u003e\n\u003cli\u003eBall bearing construction for smooth, low-friction operation under frequent cycling\u003c\/li\u003e\n\u003cli\u003eSteel base with BSP Black Suede Powder Coat finish for durability and aesthetic consistency\u003c\/li\u003e\n\u003cli\u003e4.5 inches x 4.5 inches leaf size fits standard commercial door and frame preparations\u003c\/li\u003e\n\u003cli\u003eStandard weight rating appropriate for typical commercial interior door assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style electrified full mortise hinge for standard commercial door and frame assemblies requiring an 8-wire quick connect low-voltage pass-through.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed finish hardware installer or commercial door technician familiar with electrified hinge wiring and access control integration. De-energize all low-voltage circuits before making or breaking the QC8 wire connections. The full mortise design requires precise routing of both door and frame leaves — use manufacturer templates to ensure proper pocket depth and leaf alignment. Consult applicable local building codes and the access control system manufacturer's wiring diagram before finalizing conductor terminations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Size\u003c\/strong\u003e: 4.5 inches x 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnuckle Configuration\u003c\/strong\u003e: 5-Knuckle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Type\u003c\/strong\u003e: Full Mortise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight Class\u003c\/strong\u003e: Standard Weight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: BSP Black Suede Powder Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrification\u003c\/strong\u003e: QC8 Quick Connect 8-Wire\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MCKINNEY PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mpb79 4-5x4-5 bsp qc8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MCKINNEY PRODUCTS","offers":[{"title":"Default Title","offer_id":51268103405874,"sku":"MPB79 4-5X4-5 BSP QC8","price":166.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308911865.webp?v=1780699145","url":"https:\/\/voomisupply.com\/products\/mckinney-products-mpb79-4-5x4-5-bsp-qc8-electrified-hinge","provider":"Voomi Supply","version":"1.0","type":"link"}
