NGP Parallel Arm Seals

NGP parallel arm door closer perimeter seals are ideal for high traffic doors featuring a door closer or overhead holder that require a continuous, unbroken perimeter seal to maintain a barrier against the outside elements. National Guard Products has designed perimeter seals with weather seal sections for a gasket that remains intact when installed before attaching the parallel arm closer or overhead holder.


Parallel arm series perimeter seals are available with neoprene, vinyl, or silicone bulbs, as well as nylon brushes, and feature jamb sections with slotted holes for adjustment during installation. All NGP parallel arm door closer perimeter seals are UL Listed, and some varieties are acoustical, air, and smoke tested to prevent sound, drafts, and smoke from infiltrating the space on the other side of your door.
