Flush Wall Vents

A flush wall vent sits level with the wall instead of standing off it. There is no plastic grille, no visible frame and no shadow line — the metal face mudds in during installation, takes paint or wallpaper, and the vent stops being something you notice.

Mud-in install, paint-ready finish

The outer flange is deliberately larger than the hole so it can be taped, mudded, sanded and finished like any other drywall seam. Once it is painted, the only thing visible is the slot. Metal will not warp, yellow or soften next to a warm supply duct the way a plastic register does, so the finish you paint is the finish you keep.

Eleven sizes — supply, return and exhaust

3x10, 4x8, 4x10, 4x12, 6x10, 6x12, 6x14, 8x14.25, 10x10, 10x30.25, and a 14x14 exhaust mount that takes fan housings from 8x8" up to 10.5x10.5". Singles or 5-packs. That range covers standard supply runs, oversized returns and bathroom exhaust in one finish, which is usually the hard part of a whole-home job.

Walls and ceilings both

The same vent works on a ceiling, which is where most exhaust and return grilles end up. See bathroom exhaust fan cover ideas for finished examples.

Sizing and install

Measure the bare duct opening at its widest point — not the old cover. Every size, with the duct-opening range and the front-face dimension, is in the flush wall vent size guide. Related reading: wall vent cover sizes for returns and exhausts.
