Description
A latch dust box is a small insert installed behind a door latch to cover the typically rough or splintered cutout. It provides a cleaner look and easier to clean too.
The dust box supplied with this Omnia Door Latch is 3/4" deep. Since the latch mechanism itself only requires about 3/8" of clearance, I designed this lower-profile version to reduce the required mortise depth while still fully enclosing the opening.
Included Fusion and STEP files for easy remixing.
Dimensions:
internal dimensions (box) - 32mm x 20mm
outer dimensions (flange) - 68mm x 24mm
depth - 11.1mm (~ 7/16")
Printing:
Does require supports. Print on its back with tree supports for the flange.
