Yale CA4607 Grade 2 Entrance Lock

The Yale CA4607 is a Grade 2 cylindrical knob lockset designed for commercial entrances. Its heavy-gauge steel ball knob and satin stainless finish suit metal or wood doors in office and retail buildings. The lock is three-hour fire rated and ships with two nickel-silver keys keyed different on a Para keyway.

Check Door Thickness and Backset

Verify that the door thickness falls between 1-3/8 and 1-3/4 inches and that the backset measures 2-3/4 inches. The included T-strike measures 2-1/4 by 1-1/8 inches and is sized for standard metal frames or wood frames with metal reinforcement. Confirm the existing prep matches these dimensions before ordering.

Sustained Traffic Durability

Grade 2 construction meets medium-duty cycle requirements for daily commercial traffic. The steel chassis and six-pin cylinder resist wear from repeated operation better than residential-grade hardware. Fire-rated components maintain integrity during prolonged exposure to heat, supporting code compliance in rated openings.

Questions about this item

Does the CA4607 x 630 knob lockset come with everything needed to install it on a standard commercial door?

The lockset includes the ball knob, latch mechanism, T-strike plate measuring 2-1/4 in. x 1-1/8 in., and two nickel-silver keys. No additional parts are required for a door 1-3/8 in. to 1-3/4 in. thick with a 2-3/4 in. backset.

How do I decide between the Grade 2 Series 4600 and other Yale entrance locksets?

The Series 4600 is a Grade 2, 3-hour fire-rated ball knob designed for medium-duty commercial use on metal or wood doors. Choose it when a heavy-gauge steel knob with satin stainless finish and six-pin Para keyway meets the project specification.

What does the 3-hour fire rating mean for daily operation of the CA4607 x 630?

The lockset has been tested to withstand fire exposure for three hours on rated door assemblies, so it maintains latch integrity during a fire event while functioning as a normal keyed entrance lock every day.
