Master Lock SLC0926DKA4 Classroom Lever Lockset

Product Description

The MASTER LOCK SLC0926DKA4 is a Grade 2 classroom lever lockset designed for doors up to 1.75 inches thick. It features a 6-pin Schlage C keyway cylinder and a 2.75-inch backset, making it a direct fit for standard commercial and institutional door prep. The lockset is constructed from zinc die cast with a brushed chrome finish. Cylindrical construction and removable thru-bolts support straightforward installation and long-term durability. This unit ships keyed alike, which simplifies master key planning for facilities that require multiple doors on one key. Licensed locksmiths, commercial door hardware installers, and facilities maintenance crews are the primary trades handling this lockset.

The SLC0926DKA4 is suited for classroom and institutional applications where the outside lever must remain locked unless a key is used to unlock it from outside, while the inside lever allows free egress at all times. The 2.75-inch backset matches standard door preparation found in most commercial and school-facility door frames. The clutch mechanism protects the internal drive from forced-rotation attacks, which is a common security requirement in educational and commercial settings.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI cylindrical lockset procedures. Ensure the door is fully open and all door hardware is removed before beginning installation. Verify door thickness and backset measurement before mounting to avoid misalignment of the latch and strike. Reference the manufacturer installation sheet for thru-bolt placement and latch faceplate mortise dimensions.
