Overhead Concealed Closers
Frequently Asked Questions
What is an overhead concealed closer?
An overhead concealed closer is a door closer hidden inside the door frame header, controlling swing without visible hardware. At National Lock Supply, we stock overhead closers designed for storefront and glass doors where aesthetics are critical.
How do they differ from surface closers?
Surface closers mount visibly on the door or frame, while overhead concealed closers are completely hidden, creating a seamless architectural appearance.
What door types use overhead closers?
They are typically used in aluminum storefront doors, frameless glass doors, and architectural openings, especially where appearance matters.
Are they adjustable?
Yes. Overhead closers provide adjustment for closing speed, latch speed, and backcheck, similar to surface closers.
Are they ADA compliant?
Yes, when adjusted to meet ADA opening force requirements.
Are overhead closers fire-rated?
Yes. Many are UL-listed for fire-rated doors, making them suitable for both safety and aesthetics.
Where are they installed?
In retail entrances, office lobbies, and high-traffic commercial spaces, especially where a minimal hardware appearance is desired.
What finishes are visible?
Only the arm and cover plate are visible, typically available in Aluminum, Stainless Steel, or Dark Bronze.
Do they require professional installation?
Yes. Installation is more complex than surface closers, requiring precise alignment with pivots and frame headers.
