Floor Door Closers

What Is a Floor Door Closer?

A floor door closer (also known as a floor spring or floor-mounted door closer) is a mechanical device installed in the floor beneath the door pivot point. It is designed to control the opening and closing motion of heavy commercial doors, glass storefront doors, and swinging doors while remaining completely hidden from view.

Because of their concealed design and load-bearing capability, floor closers are commonly used in architecturally sensitive environments, high-traffic entryways, and historic buildings where surface-mounted hardware would detract from the appearance of the door.

How Floor Door Closers Work

Floor closers function similarly to overhead closers but are installed beneath the threshold. A concealed hydraulic mechanism within a floor box controls the closing speed and force, while the pivot system carries the weight of the door.

Features typically include:

• Adjustable closing and latching speeds

• Backcheck to protect against slamming

• Hold-open or non-hold-open options

• 90° or 105° opening range (depending on model)

• Fire-rated models available for commercial compliance
  
  

Where Floor Closers Are Commonly Used

Floor door closers are ideal for:

• Glass storefront entryways

• All-glass commercial doors with patch fittings

• Heavy wood or metal swing doors

• Historic buildings with concealed hardware

• Double-acting doors (swing both ways)

• High-end architectural entrances

Their hidden installation and strong load support make them popular with architects, preservation specialists, and storefront installers.

Because these closers are built into the floor and often tied to custom glass or aluminum framing systems, replacing them can be complex and costly. That’s why rebuilding floor closers is often the most efficient and cost-effective solution.
