Mckinney Products Mpb79 4-5x4-5 Bsp Qc8 Electrified Hinge

Product Description

The MCKINNEY PRODUCTS mpb79 4-5x4-5 bsp qc8 is an electrified full mortise ball bearing hinge designed for access-controlled door applications. 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.

This 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.

Key Features

• QC8 Quick Connect 8-wire electrified barrel routes low-voltage wiring cleanly through the hinge
• 5-knuckle MacPro full mortise configuration for standard commercial door applications
• Ball bearing construction for smooth, low-friction operation under frequent cycling
• Steel base with BSP Black Suede Powder Coat finish for durability and aesthetic consistency
• 4.5 inches x 4.5 inches leaf size fits standard commercial door and frame preparations
• Standard weight rating appropriate for typical commercial interior door assemblies

Compatibility

Designed 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.

Installation Notes

Installation 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.
