Snap-On Interior Door Bottom Sweep Clip
A 120 mm U-channel segment that pushes onto the bottom edge of a 33–37 mm interior door (standard 1-3/8 in / 34.9 mm hollow-core) and holds itself on with angled flex fins. Its barbed lower jaw grips a 3–4 mm strip of rubber, EPDM or felt, which closes the light, sound and draft gap under a bathroom door. Butt segments end to end across the door and saw the last one to length. Optional 4 mm holes take #6 screws for a permanent fit.
