Master Lock DSC0732DKA4 Double Cylinder Deadbolt

Product Description

The MASTER LOCK DSC0732DKA4 is a double cylinder deadbolt designed for residential entry door applications. It features a 6-pin Schlage C keyway cylinder and a brushed chrome finish. The deadlocking latch mechanism provides solid resistance to forced entry. This unit accommodates door thicknesses up to 1.75 inches and installs with a standard 2.75-inch backset. It is keyed alike, making it suitable for multi-door installations where a single key must operate more than one lock. Licensed locksmiths, carpenters, and general contractors are the typical installers for this hardware.

This deadbolt is rated for residential entry doors and meets ANSI Grade 2 standards, placing it in the mid-grade security tier appropriate for interior-facing exterior doors in single-family and light commercial applications. The double cylinder configuration requires a key on both the interior and exterior sides, which is commonly specified for doors with glass panels adjacent to the lock body. The keyed-alike feature supports consistent keying across multiple entry points on the same property.

• Fits door thicknesses up to 1.75 inches with a 2.75-inch backset

Installation Notes

Installation should be performed by a licensed locksmith or qualified carpenter familiar with door hardware. Before installation, confirm door prep dimensions match the 2.75-inch backset and standard cross-bore diameter. Double cylinder deadbolts are subject to local building and fire codes that may restrict their use on certain egress doors — verify compliance with applicable IBC or local amendments before installing. Do not modify the cylinder or latch components.
