Schlage Commercial 38031609 Adapter Ring Antique Brass

Product Description

The SCHLAGE COMMERCIAL 38031609 is a 2.5-inch adapter ring designed to bridge a standard 2-1/8-inch door prep bore to accept hardware requiring a larger mounting footprint. The ring ships in an antique brass finish to match coordinating trim and hardware. At just 0.05 pounds and 0.3 inches in height, it sits nearly flush against the door face. Locksmiths, door hardware installers, and commercial contractors use this adapter when upgrading or replacing cylindrical or interconnected locksets on doors that were originally prepped to a smaller bore diameter.

This adapter ring is suited for commercial and institutional door applications where the existing 2-1/8-inch door prep does not accommodate the mounting plate of a new lockset or trim piece. It is commonly installed during hardware upgrades, tenant improvement projects, or retrofits where door replacement is not practical. The antique brass finish is appropriate for facilities specifying warm-tone architectural hardware on wood or hollow-metal doors.

Installation Notes

Installation is performed by a licensed locksmith or qualified door hardware technician. Ensure the door is secured and any existing lockset hardware is fully removed before fitting the adapter ring. Verify the adapter ring seats flush and does not interfere with latch or deadbolt operation before reinstalling the lockset trim and fasteners. Follow applicable building and life-safety codes for hardware installation in commercial occupancies.
