The SCHLAGE COMMERCIAL 38031626 is a 2.5-inch adapter ring designed to bridge the gap between a standard 2-1/8-inch door bore and a larger hardware footprint. This ring installs on the door face to provide a clean, finished appearance when the existing door prep does not fully match the escutcheon or trim plate of the replacement lockset. The ring ships individually and features a satin chrome finish for a professional look on commercial and institutional doors. Licensed locksmiths, door hardware installers, and commercial contractors typically specify this accessory during hardware upgrades or replacements.
This adapter ring is suited for commercial, institutional, and multi-family residential applications where door hardware is being upgraded and the existing 2-1/8-inch cross-bore requires a cover plate or transition ring to seat new hardware properly. It is commonly used during lockset retrofits on hollow-core and solid-core doors found in office buildings, healthcare facilities, and residential common areas. The satin chrome finish coordinates with a wide range of lever and knob trim styles in matching or complementary finishes.
Designed as an OEM-style adapter accessory for commercial door hardware installations requiring coverage of a 2-1/8-inch door prep bore with a satin chrome finish trim ring.
Installation is performed by a licensed locksmith or qualified door hardware technician. Before beginning, ensure the door is secure and all existing hardware is removed. The ring is positioned over the existing bore and seated against the door face prior to mounting the lockset or trim plate. Follow applicable building codes and the lockset manufacturer's instructions for proper hardware assembly and fastener torque.
