DRIWON DN-9500 Grade 1 – a door closer for hospital doors engineered for 24/7 duty: corridors, patient rooms, smoke barriers, stairwells and emergency exits. Controlled closing, positive latching and UL fire-rated performance on rated assemblies.
Designed for hospitals, clinics, surgery centers and medical office buildings across the U.S.
Patient room, corridor & emergency doors
Tested beyond 2 million cycles
Smooth, ADA-adjustable closing
On rated door assemblies




For hospital corridor doors and patient room doors, specify an ANSI/BHMA A156.4 Grade 1 hydraulic surface closer with adjustable power, separate control of closing speed and latch speed, and a delayed-action option. Grade 1 hardware is the right class for doors that cycle all day and night, and an adjustable size 1–6 closer lets facilities teams tune each door to its weight, width and air-pressure conditions.
Under the 2010 ADA Standards for Accessible Design (section 404), interior hinged doors must open with no more than 5 lbf, and a closer must be adjusted so the door takes at least 5 seconds to swing from 90° to 12° from the latch. Fire doors are the exception on opening force: the authority having jurisdiction sets the minimum. Always check local code and your AHJ.
Closers also support infection control workflows. A reliably self-closing, latching door helps maintain separation between clean and soiled zones and supports the pressure relationships designed for isolation, procedure and sterile areas. A closer does not replace pressure monitoring, but a door that stands ajar defeats the HVAC design. The DN-9500's non-porous powder-coated finish can be wiped down; verify compatibility with your facility's disinfectants.
Hospitals rely on compartmentation: smoke barriers, horizontal exits, stairwell enclosures and corridor walls. Doors in these assemblies must be self-closing and positively latching under NFPA 80 and NFPA 101, and the hardware must be listed for use on the door. The DN-9500 is UL listed and 3-hour fire rated when installed on a rated wood or metal door assembly. Confirm the door label, the frame, and the AHJ requirements for every opening.
This pairs with a hospital door lock specification: choose locks and latches first, then size the closer to reliably seat that latch.
Health institutes and design teams often ask about hidden door closers. The right choice depends on the door, the code and the maintenance plan.
| Visible (surface-mounted) | Hidden (concealed) | |
|---|---|---|
| Location | On the door face or frame, in plain view | Inside the door leaf, the frame head or the floor |
| Look | Visible body and arm | Clean, minimal appearance |
| Installation | Simple; no cutting of the door or frame | Needs door or frame preparation, usually done at fabrication |
| Service | Easy to see, adjust and replace | Harder to access; adjustment may be limited |
| Door weight and size | Wide range, including very heavy doors | Often limited by the product and the door |
| Fire rated doors | Widely listed for rated assemblies | Only if listed for the specific door and frame |
| Cost | Lower | Higher |
For hospital corridors, stairwells, back-of-house and medical building doors, visible closers are the practical default because they are strong, inexpensive and quick to maintain. The DN-9500 is a visible surface-mounted closer. If your project calls for concealed hardware, specify a product listed for the door and frame, and contact us for help with the visible options.
Hospital revolving doors use their own drive and braking system, not a door closer. Because revolving doors are not accepted as the only means of egress or accessible entry, they are normally paired with an adjacent swinging or automatic door. That swinging door, and the many manual doors inside the building, are where a closer belongs.
For healthcare door opening solutions, many hospitals combine low-energy automatic operators at patient entrances and key corridors with Grade 1 closers on manual, fire-rated and back-of-house doors. Where an operator is installed on a fire door, the door must still close and latch as designed, so check the listing for the full assembly.
In behavioral health units, hardware must reduce places where a cord or fabric could be attached. Anti-ligature closers and hardware are designed for that purpose, often with concealed or tightly integrated bodies and sloped surfaces. The DN-9500 is a standard surface closer and is not an anti-ligature product. Use it on staff corridors, nurse stations, pharmacy, storage and support doors, and use anti-ligature rated hardware in patient-accessible behavioral health areas.
Healthcare campuses include more than the hospital itself. Outpatient clinics and medical office buildings have their own occupancy rules and door population, senior living communities prioritize low opening force and delayed action, and hospital garages add pressurized and exposed doors.

A visible closer is mounted on the face of the door or frame and is easy to service. A hidden closer sits inside the door, frame or floor for a cleaner look but needs preparation and can be harder to service. The DN-9500 is a visible surface closer.
No. Revolving doors have their own drive and braking systems. Door closers are used on swinging doors, including those that sit beside a revolving door.
Yes, anti-ligature closers exist for patient-accessible areas. The DN-9500 is not anti-ligature rated and is intended for staff and support doors.
A Grade 1 heavy duty hydraulic closer with adjustable power size 1–6, controlled latch speed and a durable arm, such as the DRIWON DN-9500. It is built for the constant cycles of corridor traffic.
The DN-9500 is adjustable so you can set closing time and opening force to meet ADA section 404 limits for the specific door. Final compliance depends on installation and the door assembly.
Yes. The DN-9500 is UL listed and 3-hour fire rated when installed on a rated door assembly. Check the door label and local code.
It is suited to staff and support doors. It is not anti-ligature rated, so use anti-ligature hardware in patient-accessible behavioral health areas.
Doors from 44–440 lbs and 23"–59" wide.
A Grade 1 closer with ADA adjustment and delayed action on suite entries, and UL listed closers on rated doors. See our medical office building page.
Yes, within its 440 lb rating, when the hinges or pivots are rated for the door weight.
