Yale Storeroom Lockset
This Yale CA4605 630 knob lockset is a Grade 2 mechanical cylindrical lock designed for commercial storeroom doors. It operates with a key from the outside and a fixed interior knob, so the outside remains locked at all times. The heavy-gauge steel ball knob and satin stainless steel finish suit high-traffic metal or wood door installations. It carries a three-hour fire rating and meets ANSI A156.2 standards.
Suited for always-locked exterior doors
The storeroom function fits doors that must stay secured from the outside while allowing free egress from inside, such as storage rooms, utility closets or server rooms. It is not for offices or classrooms that need push-button locking from the interior, nor for residential entry where a thumbturn or privacy function is preferred. The Yale Para keyway and nickel-silver keys work with existing Yale master-key systems but will not match other keyway families.
Grade 2 commercial duty
The lock is certified to ANSI A156.2 Grade 2, the benchmark for standard commercial traffic. This single grade rating determines whether the hardware meets the durability and cycle requirements of your building specification.

Questions about this item
Does the mechanical push-button design of the CA4605 generate any noise or heat during continuous daily operation?
The lockset operates mechanically with no electronic components, so it produces no operational heat and only minimal sound from the latch bolt engaging during use.
What door preparation must already exist for the CA4605 storeroom knob to install correctly?
A cylindrical bore with a 2-3/4 inch backset is required, suitable for metal doors with metal frames or wood doors with wood or metal frames.
Will the Yale Para keyway on the 4605 cylinder work with existing Yale 4000 series key systems already in the building?
The cylinder uses the Yale Para keyway, which is the standard keyway for Yale 4000 series cylinders, allowing integration into existing master-key systems using that keyway.
