What This Article Covers -- and Who It Helps
A double-acting door swings freely in both directions from a centered rest position rather than stopping at a frame stop like a conventional single-acting door. That fundamental difference changes nearly every component in the hardware set: the pivot system, the closing device, the edge treatment, and the push-pull trim. If you are a contractor building out a restaurant kitchen pass-through, a facility manager replacing worn-out saloon-style doors in a school cafeteria, or an architect specifying corridor doors in a busy healthcare environment, this guide walks through what a complete double-acting hardware set actually requires -- and where specifiers most often get it wrong.
What Is a Double-Acting Door?
A double-acting door (sometimes called a swing-clear or saloon door in lighter applications) is hung on a center-hung pivot system so the door's pivot point runs through the center of the door thickness rather than at the hinge edge. This allows the door to swing 90 degrees in either direction and return to a neutral closed position under spring or hydraulic control. Because there is no fixed frame stop, the door cannot be sealed against a rabbet the way a single-acting door is -- and that changes everything downstream in the hardware set.
Common applications include:
- Commercial kitchen pass-through openings (restaurants, cafeterias, hospital food service)
- High-traffic corridor doors in schools and healthcare facilities
- Industrial plant floor openings where carts and equipment move in both directions
- Retail stock room entries
The Pivot System: Center-Hung Is Not Optional
The foundation of any double-acting hardware set is the center-hung pivot. Unlike an offset pivot used on single-acting aluminum storefront doors, a center-hung pivot locates the spindle at the centerline of the door thickness -- typically at 2-5/8 inches from the outside edge. The pivot set consists of a top pivot (often a smaller tension or non-handed unit) and a floor-mounted bottom pivot or floor closer that carries the door's weight and controls the return swing.
For heavy commercial doors, a floor closer in the double-acting configuration provides both the pivot point and hydraulic closing control. Non-handed, center-hung floor closers are available in wood-door and hollow metal configurations and can serve single or double-acting operation depending on how internal valves are set. The non-handed nature of center-hung pivots is a practical advantage: no hand needs to be declared at the time of order, which reduces lead-time risk on projects where the door schedule is still being finalized.
Key pivot and floor closer considerations
- Verify the floor-closer body fits within the floor construction depth -- recess depths vary by model and substrate
- Cement cases are available for poured concrete applications; wood-door models use a different fastener pattern
- The top pivot must be compatible with the floor closer series -- mixing manufacturers without confirming compatibility risks misaligned spindle centerlines
- For very heavy doors, an intermediate pivot can be added to carry additional load
Closing Devices: Floor Closers vs. Overhead Concealed Closers
Two hardware categories control the return action on a double-acting door: floor closers and overhead concealed closers.
Floor closers are the most common choice for heavy double-acting doors. The hydraulic unit is set into the floor below the door, keeping the closing mechanism completely concealed. Closing speed, latching speed, and back-check are typically field-adjustable. Norton Rixson's center-hung floor closer lines (the W30, W40, W50, H40, and related series) are widely referenced in the industry for aluminum and wood door double-acting applications and illustrate the range of options available by door weight and substrate.
Overhead concealed closers mount into the top rail of the door and the head frame. The Norton Rixson 608 series and MW800 series, for example, are designed specifically for center-hung double-acting applications in aluminum and wood doors respectively. Overhead units are preferred when floor construction cannot accommodate a recess, or when the aesthetic of a fully above-floor installation is required. Brands such as Hager and Corbin Russwin offer comparable overhead concealed closer lines worth specifying when a stable, service-friendly product is a priority.
Choosing between floor and overhead
- Floor closers are generally better for very heavy doors and high-cycle applications (industrial, cafeteria)
- Overhead concealed closers are preferred when the floor slab is already poured and coring is not feasible
- Both types require confirmation that the door top or bottom rail is deep enough to accept the unit -- minimum rail depths vary; always check the template before the door is ordered
Edge Prep: Radius Stiles and Door Edging
A double-acting door cannot have a standard square or beveled lock edge -- it needs a radius stile on both the latch edge and the hinge edge so it can swing past the frame opening cleanly in either direction without binding. The radius is typically 2-5/8 inches, matching the standard center-hung pivot centerline dimension.
Door edging applied to the stile edges of a double-acting door is generally used on both edges -- not just the push side as with single-acting doors. This protects the exposed radius stile from wear and impact, which is especially important in industrial and food-service environments where carts and equipment contact the door repeatedly.
If armor plate is specified on a double-acting door, it is typically required on both faces rather than just the push side. Confirm this with the door manufacturer before fabrication.
Trim: Push-Pull Sets Instead of Lever Hardware
Because a double-acting door has no frame stop and no traditional latch, push-pull trim is the standard solution. A centered push plate or pull handle on each face allows users approaching from either direction to operate the door without reaching for a lever or knob that would not make functional sense on an unlatched, free-swinging door.
For openings that require a hold-closed or latch position -- common in food service where odor and temperature separation matter -- a spring latch or roller latch designed for double-acting doors can be added. These latches are distinct from standard mortise latches and are designed to engage a centered or top-mounted strike that works regardless of swing direction.
ADA and Accessibility Considerations
Double-acting doors present a challenge under ADA and ICC A117.1 accessibility requirements. A free-swinging door without a hold-open position and with significant return spring force can be difficult or impossible for wheelchair users and people with limited strength to navigate safely. For accessible routes, coordinate with the project AHJ on whether the opening can be double-acting or whether an automatic operator or single-acting door is required. Closer spring force and opening force limits still apply to any door on an accessible route, even when a concealed floor closer is used.
Putting the Hardware Set Together
A complete double-acting hardware set typically includes:
- Center-hung floor closer or overhead concealed closer (non-handed, double-acting capable)
- Top pivot (non-handed, compatible with closer series)
- Radius stile door edge treatment on both stile edges
- Push-pull trim on both faces
- Armor plate or kick plate on both faces if impact protection is required
- Spring latch or roller latch if hold-closed function is needed
What it does not include: standard butt hinges, a conventional mortise lockset, a surface-mounted closer with arm, or single-face push plates. Getting any of these into a double-acting hardware set is a common scheduling error that delays the opening.
