Yale CA5405CK-630 Storeroom Knob Lockset Grade 3

Product Description

The YALE CA5405CK-630 is a Grade 3 storeroom knob lockset designed for doors with a thickness of 1-3/8 inches and a 2-3/4 inch backset. Built with a bronze body and a stainless steel finish, this lockset features a 2-cylinder configuration that keeps the exterior knob locked at all times, allowing entry only by key. Egress from the interior side is always free without a key. At 3 pounds, it is a solid, function-specific unit appropriate for light commercial and residential storeroom or utility room applications where controlled access is required.

This lockset is suited for storeroom and utility door applications in light commercial buildings, multi-family residential properties, and institutional settings. The storeroom function means the outside knob is permanently locked and can only be unlocked by key, making it ideal for supply closets, storage rooms, and server or equipment rooms where staff access must be controlled. It fits standard pre-bored door prep with a 1-3/8 inch door thickness and a 2-3/4 inch backset.

Installation Notes

Installation is typically performed by a licensed locksmith or qualified facilities technician following the door hardware manufacturer instructions and applicable local building codes. Ensure the door is pre-bored to the correct specification before installation and that the door is closed and the latch fully retracted before seating the latch bolt assembly. Do not force the knob mechanism during installation as this may damage the cylinder. Verify key function and latch operation before returning the door to service.
