L/Arden filter track installation provides a quick and professional filter placement system. Two styles are available to accommodate either a side connection or internal placement within a duct. Made of aluminum extrusion guarantees that the track will be straight and free of sharp edges that could hinder filter removal and replacement. Filter tracks come in various lengths, and should be mitre cut to the required size. Once cut, the track can be easily assembled with the enclosed corner keys and fastened into place. Custom sizes and quantities can be factory ordered, completely assembled with corner keys welded into place.
