Flush Floor Vents

Flush floor vents sit level with your flooring — no raised edges to catch a toe, a vacuum, or your eye. Khan Supply CO builds all-metal flush mount floor registers in two install styles:

Drop-In (retrofit-friendly). Our best-selling Drop-In Floor Vent clicks into your existing vent opening — no tools, no screws, no subfloor work. A raised interior plate delivers up to 60% more airflow while the frame sits low-profile against the floor. The Upgraded 2-in-1 version adds a removable matte-black insert, or drop in a piece of your own flooring for a nearly invisible finish.

Undermount (fully flush). Our Signature Undermount Flush Floor Vent mounts beneath the floor surface so the grille sits perfectly level with hardwood, tile, or vinyl plank — the cleanest built-in look for new builds and full renovations, with an adjustable damper for airflow control.

Every vent is heavy-gauge metal — nothing plastic to warp, melt, or rattle. Sizes 3x10, 4x10 and 4x12 in matte black or white, with multi-pack savings. Free shipping across Canada and a 2-year warranty on everything.
