    This automatic door bottom is designed to be fully mortised within the hollow interior of the door. The high quality, durable, neoprene seal is housed within a strong, .062” thick, aluminum casing.

    Its mortised application allows the door to maintain a clean, unobtrusive appearance, making it an optimal choice for high-end designer doors and luxury hotels and condos.

    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 closing force to actuate the drop-bar seal.

    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. Door hang-up will not occur! Choose the correct swing direction from the drop-down box above. This door bottom  is rated for 5 million cycles.

    About Light Spring Strength: Light Spring Strength requires less operating force to activate than standard Strength. Light Spring is compatible with ADA Compliant Doors and can be easily used by those with limited mobility. Casing dimensions remain the same. To purchase, select from options above.
