This drop-down seal system prevents air infiltration around door perimeters in office buildings, hotels, dormitories, and upscale residential projects. \u003ca href=\"\/companies\/pemko\"\u003ePemko\u003c\/a\u003e designed this unit to mount completely within the door thickness so it does not affect the door's appearance or interfere with floor finishes.\u003c\/p\u003e\n\n\u003cp\u003eThe aluminum housing mortises into doors from 1-3\/8\" to 1-3\/4\" thick. When the door closes, the PemkoPrene seal automatically drops down to contact the floor and create an airtight barrier. The seal retracts when the door opens. This automatic operation eliminates manual adjustment and ensures consistent sealing performance. Different end plate kits accommodate various door thicknesses.\u003c\/p\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAnodized Aluminum Housing, PemkoPrene Seal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eFull Mortise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e36 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDoor Compatibility\u003c\/th\u003e\n\u003ctd\u003e1-3\/8\" to 1-3\/4\" thick doors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eMill Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e5 Years Limited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eThis door bottom meets UL 10C positive pressure fire testing standards for \u003ca href=\"\/resources\/building-codes-standards\/fire-inspection-compliance\/ul-10c-fire-rated-doors\"\u003efire door assemblies\u003c\/a\u003e and UL 1784 air leakage requirements.
