Description
The Marks USA 5 Series mortise lock body is a replacement chassis for doors already prepared for this series. It fits the 1-1/4 by 8 inch front with 2-3/4 inch backset, dropping into the existing pocket without requiring door re-mortising. This body renews the latch, deadbolt, and internal components while preserving your existing trim and cylinders when compatible.
Confirm function and handing before ordering, and contact our team at sales@edlocks.com or 1-877-207-6067 with a photo of your old case front if you need guidance. As an authorized dealer, we help you select the correct replacement and ensure smooth installation, turning a potential door rebuild into a quick twenty-minute repair.
