Security Check


  • Additional Product Details
    Automatic door bottoms comprise an aluminium case surrounding a movable drop bar seal. The drop bar seal is actuated by a plunger that contacts the jamb as the door closes, forcing it down against the floor or threshold.

    • When the plunger contacts the jamb, the drop bar seal actuates first from the hinge side, allowing multiple compression points.
    • The plunger requires low "FeatherTouch" closing force to actuate the drop bar seal. The "L" at the end of all product numbers stands for Low Closing Force
    • End plates are provided for all mounting applications
    • Available in sizes ranging from 457mm to 1829mm
    • All Pemko automatic door bottoms are provided net length
    • Stock length automatic door bottoms can be trimmed as much as 50mm


    Drop-Bar Seal Actuation

    The drop bar mechanism prevents the seal from skidding along the floor or threshold when the door is closed.

    Important Drop Bar Information

    Drop seals of all types are designed to close a uniform-size gap. Pemko drop seals can seal up to 19mm gaps, provided the gap is consistent. Gaps that start at less than 19mm and then grow cannot be closed. The drop seal utilizes a straight aluminium extrusion, so it cannot close an inconsistent gap.

    For disabled people to have independent access through single or double swing doors, the opening force, when measured at the door's leading edge, must not exceed 30N between 0º and 30º from closed and 22.5N until 60º. This performance requirement might be impossible for some locations where closer forces and the influence of seals used for smoke sealing or acoustic performance requirements will add to operating forces.

    We provide an extensive range of threshold drop seals that may be used for smoke sealing purposes (where the under door gap
    exceeds 3mm) or for sound attenuating, light tight or other performance requirements. All our threshold drop seals incorporate Pemko’s patented low friction ‘Feather Touch’ technology, resulting in minimal operating forces.

    Optimum performance is achieved when the seal is adjusted to grip a 50-70 gsm piece of paper that can be withdrawn without tearing. Unless otherwise specified, the seal element consists of a closed-cell sponge neoprene insert to Pemko’s patented ‘tri-fin’ design. The seal maintains flexibility down to -70°F and benefits from good ‘memory’ and durability characteristics. Other seal element options are available where specified.
