As the door closes, the mechanism automatically drops a seal against the floor, then retracts when the door opens. The unit ships at 37 inches in length to allow field trimming to fit a 36-inch door. The body is mill finish aluminum, and the seal insert is PemkoPrene, a resilient gasket material suited for weather and air infiltration control. Licensed contractors and commercial door hardware installers are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThe 434APKL36 is intended for commercial and residential door applications where a mortised automatic door bottom is specified. It is recessed into the bottom rail of the door face, making it appropriate for new construction and retrofit projects where a flush, concealed appearance is required. Typical applications include exterior entry doors, corridor doors, and other openings where weather sealing, sound attenuation, or smoke control at the door bottom is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull mortise design mounts flush into the door bottom rail for a concealed profile\u003c\/li\u003e\n  \u003cli\u003eAutomatic drop-seal mechanism activates on door closure and retracts on opening\u003c\/li\u003e\n  \u003cli\u003ePemkoPrene seal insert provides durable resistance to weather and air infiltration\u003c\/li\u003e\n  \u003cli\u003eMill finish aluminum body resists corrosion in commercial door environments\u003c\/li\u003e\n  \u003cli\u003eShips at 37 inches length to allow field trimming to a 36-inch door width\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation automatic door bottom for full mortise applications on standard 36-inch commercial and residential doors.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified door hardware technician or finish carpenter. The door must be removed from the frame and the bottom rail routed to accept the mortise housing before the unit is set.
