Classroom Function Knob Lockset

This mechanical lockset serves classroom doors where the outside knob locks with a key and the inside knob always allows free egress. It fits medium-duty commercial and institutional applications that require Grade 2 durability.

Standard Cylindrical Installation

The lock fits a 2-1/8 inch crossbore with a 2-3/4 inch backset on doors 1-3/8 to 1-3/4 inches thick. Misaligned crossbores or incorrect door thickness are the most common issues that prevent proper latch engagement.

ANSI Grade 2 Fire-Rated Hardware

Certified to ANSI 156.2 Series 4000 and UL-cUL listed for three-hour fire doors, this lockset meets life-safety requirements for corridor and stairwell openings. Buyers needing Grade 1 strength or electronic access control should specify a different product.

Questions about this item

How do I verify the lockset meets the ANSI 156.2 Grade 2 standard after installation?

Check that the latch retracts smoothly with the key from outside and the turn button inside, and confirm the 3-hour fire rating label is visible on the latch edge.

What components come with the CA4608 x 630 lockset and what must be purchased separately?

The box includes the knob lockset with 4600 ball style, satin stainless finish, two keys for the Para keyway, and a 2-3/4 x 1-1/8 in. strike; no additional parts are required for standard 1-3/8 to 1-3/4 in. doors.

Which keying option should I choose for multiple classroom doors needing different keys?

Select the Keying Different (cylinder 1805) version so each lockset operates with its own unique key.
