Description

This heavy duty automatic door bottoms creates a strong seal, preventing fire, smoke, sound, drafts, dust, light moisture and insects from penetrating the gap under doors. Custom cut to size.

How it works: The high quality automatic mechanism consists of an aluminum case which surrounds a moveable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the door frame jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold. The plunger requires low "Feather Touch" closing force to actuate the drop-bar seal. The seal drops to fill gaps up to 3/4". The mechanism causes the seal to always actuate on the hinge side first, which prevents the seal from skidding along the floor/threshold while the door is being closed (See Application Tab). Door hang-up will not occur!

Seal: This automatic door bottom comes equipped with a double nylon brush seal and aluminum stop. The brush conforms well to surface irregularities and can be used on uneven surfaces. The bristles remain flexible in extreme weather, making it ideal for external doors. The aluminum stop is lowered simultaneously with the brush to prevent it from bending too far back and ensure a proper seal is maintained.

Installation: This automatic door bottom is fully mortised, and will not be seen on the face of the door, making it ideal for high end, luxury doors. Size of casing differs according to length, review product specs before purchasing. Door bottom can be trimmed up to 2".

Door Thickness: Model is compatible with minimum 1-3/4" thick doors.
