The BMP size adjustable air handler base/stand allows both the wholesaler and contractor to stock a single stand to cover most of their size requirements. This is the only stand to ship flat in a box, saving space in both the warehouse and the technician’s van. It is easy to load and transport to the job location and takes only seconds to assemble with the bolts provided. Straight flush corners allow efficient space usage in tight closets. All stands have built-in filter slots and include foam seal strips. Powder-coated paint looks great and resists rust.
