Commercial Entry Hardware

The MAXTECH IC13041 is a Grade 2 interchangeable-core entry knob set finished in Polished Brass US3. It suits commercial doors 1-3/8" to 1-3/4" thick with a standard 2-3/4" backset. The reversible, non-handed design works for both right- and left-hand installations. The core is sold separately, allowing facilities to integrate existing 6- or 7-pin IC cylinders.

Sustained Access Control

Under daily commercial traffic the push-button locking on the inside and keyed entry outside maintain consistent operation. The 1/2" latch retracts smoothly from either knob when unlocked, while the Grade 2 construction resists wear from repeated cycles. Because the core is removable, re-keying or master-key changes can be done without removing the trim from the door.

Core Compatibility Decides Fit

This lock accepts 6-pin IC cores such as model 626 and 7-pin cores such as model 726, but ships without a cylinder. Buyers who need a complete locking solution must source a compatible core separately. If your project requires an included cylinder or a different backset, this trim set will not meet that requirement.

Questions about this item

How much heat or noise does the lock produce after being used continuously all day?

The lock is a purely mechanical device with no motor or electronics, so it generates no heat and makes no audible noise during normal operation.

What additional parts must I already have for this lock to function?

You need a compatible 6-pin or 7-pin interchangeable core — Maxtech models 626 or 726 — because the core is sold separately and the lock cannot operate without one.

Will the 2-3/4" backset and 1/2" latch work with the older door prep I already have?

Yes, if your existing door has a 2-3/4" backset bore and accepts a 1/2" latch, the lock fits directly; it also covers door thicknesses from 1-3/8" to 1-3/4" and is reversible for left- or right-hand openings.
