I am looking for an air filter holding frame. I believe they were called "Zip Lock" filters. The holding frame cross section was shaped like a "Vee" and it was make of plastic, possibly lexan. You used a wide about a ¼-inch wheel "pizza cutter" to insert blanket filter media into the frame. The filter media could be standard blanket filter to a two (2)-ply media with a tacifier on the leaving side of the filter.

The holding frames could be configured into flat or vee shaped with a filter media width of approximately 40 inches, between frames. The filter media was held in to place by the "Vee" shaped holding frames on the four (4) edges and about a 12-gauge aluminum wire "laced" between the holding frames to support the media.

If the holding frames were properly installed and caulked into place, this filter system eliminated almost all bypass around the filters. They were used extensively for telephone equipment room AHU's.
