Prime-line MP4148 Patio Door Pin Lock

Product Description

The PRIME-LINE MP4148 is a pin lock designed for patio door applications. Pin locks provide a secondary security point by inserting into a pre-drilled hole in the door frame or track, preventing the door from being lifted or slid open even when the primary latch is defeated. This type of hardware is a standard replacement component in residential patio door maintenance and is typically installed by general contractors, handymen, or knowledgeable homeowners performing door hardware service.

The MP4148 is suited for patio door installations requiring a replacement or supplemental pin lock. It fits into common patio door track and frame configurations where a pin-style secondary lock is specified. This unit is sold individually, making it appropriate for single-door repair or upgrade work without requiring purchase of a multi-pack.

Key Features

• Pin lock design provides secondary security for patio door assemblies
• Replacement-grade component for patio door hardware maintenance

Compatibility

Installation Notes

Installation is typically performed by a general contractor or experienced DIYer familiar with door hardware. Before installing, ensure the patio door panel is fully closed and the primary latch is engaged. Confirm the existing or new pin hole in the door frame or track is properly aligned with the lock body. Follow all applicable local building codes regarding door security hardware.
