K-Trac Housing

K-Trac filter framing modules are used for ASHRAE rated filters 2 in. to 36in. in depth. K-Trac Modules are complete factory-design units which replace multiple filed-erected holding frames. They also provide inherent structural strength and leak proof assembly that is sometimes lacking in frame type installations.

K-Trac framing members are factory-cut to length, pre-drilled and gasketed for easy and quick assembly. Simple tools are light labor and all that is required. Filters are easily inserted or removed and require no clips or fasteners. Filters are angled into the upper track, then set into the lower track.
