Trim ring for 1-1/8 diameter cabinet lock is a brass trim bezel from Olympus Lock, Inc. that finishes the visible edge around a cabinet lock bore. The bright brass finish defines the lock perimeter so the installation looks intentional on laminate or wood. By covering chips or gouges in the hole that can be seen from the outside of the cabinet, this ring turns a rough bore into a clean lock opening. The brass material gives a consistent appearance around the lock body, so the lock face and surrounding trim read as a single unit. Because it is a dedicated trim bezel, it focuses on the cosmetic side of the lock installation rather than the locking function. This keeps the functional lock body separate while still delivering a neat face for the cabinet.
This trim ring is sized for 1-1/8 diameter cabinet locks, so it is intended to sit around the standard round hole created for those lock bodies. That sizing allows the bezel to mask rough drill edges that remain visible after the lock is installed. Because it is a trim bezel, it occupies the face side around the lock rather than the structural part of the lock case, which leaves the installer free to use the same boring pattern already established for these locks. The bright brass finish ties the visible edge of the bore to bright brass lock faces or nearby hardware, supporting a consistent appearance across multiple cabinet fronts.
This brass trim ring is used on cabinet doors or drawers where a 1-1/8 diameter cabinet lock has been bored through laminate or wood. In those locations it covers chips or gouges in the edge of the hole that would otherwise stand out when the cabinet is closed. The ring fits around the lock body for 1-1/8 diameter cabinet locks, so it works wherever that size lock bore is present. It belongs in projects that use Olympus cabinet locks identified in the 700, 800, 850, 950, 721, 725, 754, 854, 777, 888, 931, L72, L78, and L92 families, giving installers a defined set of locks where this trim bezel matches the stated use. Because it sits at the outside face of the cabinet, it is most relevant in visible casework where the lock position is at eye level or on finished fronts.
The Olympus Lock, Inc. TR78-US3 designation ties this trim ring to a specific brass trim bezel, which simplifies selecting the same part whenever those Olympus lock models are specified. Using a ring that fits 1-1/8 diameter cabinet locks means the bezel aligns with the lock bore without changing drilling dimensions, reducing rework on doors and drawers. The bright brass finish on the trim ring frames the lock cylinder, so even if the hole edge in laminate or wood has minor flaws, the installation still reads as a controlled, finished opening. Pairing this trim ring with compatible Olympus locks such as the 700, 800, 850, 950, 721, 725, 754, 854, 777, 888, 931, L72, L78, and L92 models keeps the appearance consistent across a job that mixes different cabinet lock types. The brass material maintains a solid metal boundary around the lock face, giving the front of the cabinet a defined hardware detail rather than an exposed drilled hole.
