This Zero International #3551, automatic door bottom is designed to be mortised within the hollow interior of metal doors. Built to last, the strong, durable aluminum casing contains a high quality neoprene seal insert which effectively seals a gap of .5” beneath the door greatly reducing infiltration of light, sound, dirt, and drafts. Custom cut to size.
