Installation Guides

Step-by-step installation guides for every Khan Supply CO vent and drain — drop-in and undermount floor vents, flush and framed wall vents, and the linear shower drain. Each guide covers tools, prep and the order of operations, with photos at every step.

Sizing rather than installing? Start with the size guides — measure your duct opening, not the old cover, and match it to the range for the size you want: drop-in floor vent sizes, undermount floor vent sizes, framed wall vent sizes and flush wall vent sizes.
