Interior Trim Specifications and Cylinder Compatibility
Single cylinder interior trims install on existing door bores and latch assemblies, allowing keyed control from the interior side only. Installation requires accurate bore diameter, backset measurement, and cylinder type verification. These components integrate with standard mortise locks or tubular latches, making them essential for retrofit work and OEM-direct replacement scenarios.
Correct Bore and Cylinder Type Identification
Identify your current handleset by door bore diameter, backset distance (typically 2-3/8" or 2-3/4"), and cylinder keyway profile. Single cylinder trims accept cylinders with specific keyways—verify your existing key or cylinder before ordering. Incorrect cylinder type results in non-functioning locks and costly rework.
Backset and Latch Assembly Compatibility
Measure backset from the inside edge of the door to the center of the bore. Single cylinder trims mount to existing latches and require the correct bore size—typically 2-1/8" for the cylinder and 1-3/8" for the latch. Confirm door thickness, frame material, and interior escutcheon clearance before installation to avoid fitment issues.
