Yale CA4602 630 Privacy Knob Lockset

The Yale CA4602 630 is a Grade 2 privacy knob lockset built for commercial doors. Its 4600 ball-style knob uses heavy-gauge steel with a satin stainless finish and a six-pin cylinder. The lock fits metal or wood doors between 1-3/8 and 1-3/4 inches thick and carries a three-hour fire rating.

Upgrading from residential or Grade 3 hardware

This lockset replaces lighter residential knobs or Grade 3 units where codes require ANSI/BHMA A156.2 Grade 2 performance. The jump is worth it when a project demands a three-hour fire rating, ADA-compliant lever operation, and a T-strike sized 2-1/4 by 4-7/8 inches for metal frames.

Suited for commercial privacy doors

It suits offices, restrooms, and other interior rooms needing a privacy function on metal or wood doors with metal or wood frames. Builders needing an entry, storeroom, or passage function should look at a different lockset. Projects requiring Grade 1 certification or a backset other than 2-3/4 inches will need alternative hardware.

Questions about this item

What door thickness range does the 4602 knob lockset require for installation?

This lockset fits doors from 1-3/8 in. to 1-3/4 in. thick, covering standard commercial wood or metal doors with wood or metal frames.

Which step is often missed when fitting the T-strike on a metal frame?

The 2-1/4 in. x 4-7/8 in. T-strike must be mortised flush into the frame; surface-mounting it prevents the latch from engaging fully.

When will the 6-pin cylinder need rekeying or replacement?

Rekey the 6-pin cylinder whenever key control changes — lost keys, staff turnover or a master-key update — otherwise the Grade 2 mechanism is rated for heavy commercial cycles.
