A fire door is not a single part but a system of hardware working together. For the door to do its job during a fire, the leaf and frame plus the hinge, lock, panic bar, seal, threshold and every other accessory must all work in harmony. Each component carries out a specific task so the door self-closes, seals and operates safely. On this page you will find all the hardware and accessories that make up a Dimak fire door, what each component does, and links to the detailed technical pages.

Each item works as part of the whole. The door’s overall fire resistance performance and certification are determined by testing the complete system together. If you want to understand how the door works, start with our what is a fire door guide, and see fire door features for the key performance characteristics.

Closing and Movement

  • Spring Hinge: A single-axis hinge that self-closes the door. A spring inside the hinge provides the closing action without needing a separate door closer. EN 1935:2002 compliant, 80/100 kg door weight, suitable for right and left hand.
  • Door Closer (Standard and Sliding): Standard closing is provided by the spring hinge; a door closer can also be specified depending on project requirements.

Locking, Access Control and Lever Hardware

  • Lock: The main locking hardware that keeps the door closed and secure.
  • Cylinder: The cylinder mechanism providing keyed access control.
  • Handle: The core hardware for opening and closing the door in daily use.
  • Knob: A round opening option that can be chosen instead of a lever handle.
  • Long Pull Handle: A long handle that improves ergonomics, especially on the pull side.
  • Push & Pull Plate: A plate that protects the surface and eases operation on high-traffic doors.
  • Electrical Strike: Electrified hardware that lets the door integrate with access control, card and remote-release systems.
  • Bolt / Bolt Lever System: The bolt hardware that locks the fixed leaf on double-leaf doors.

Emergency Egress Hardware

A panic bar (emergency exit device) lets people open the door from the inside in a single push, in the direction of egress, in occupied areas. You can review our panic hardware solutions under two headings: the single leaf panic hardware fire door and the double leaf panic hardware fire door. For frame options, see the full frame fire door page.

Sealing and Protection

  • Weather / Brush Seal: Closes the gap between door and frame to support smoke and air tightness.
  • Stainless Steel Threshold: A durable, hygienic stainless steel threshold that closes the gap under the door.
  • Earthing Strip: Hardware that provides electrical continuity between the leaf and the frame.
  • Door Stopper: A stop that prevents the door from over-opening, protecting the hinge and the door.

Finish and Glazing

Modular Construction and Optional Accessories

Dimak fire doors are built on a modular construction principle, so different hardware and accessory combinations can be configured per project. Alongside the standard hardware, project-specific optional accessories can be added. To learn about the production and installation process, see fire door installation, and keep hardware performing reliably with periodic maintenance and inspections.

Frequently Asked Questions

What hardware does a fire door consist of?

A fire door consists of hardware such as a spring hinge, lock and cylinder, handle or knob, a panic bar where needed, seal, threshold, earthing strip and stopper. Together these components let the door work as a system.

How does a fire door close by itself?

On Dimak fire doors, self-closing is provided by the spring inside the hinge. In the standard configuration no separate door closer is required; a door closer can be specified additionally depending on project requirements.

Can a panic bar be fitted to a fire door?

Yes. In areas requiring emergency egress, a panic bar (emergency exit device) can be integrated into single-leaf or double-leaf fire doors.

Can a fire door be connected to an access control system?

Yes. With an electrical strike, a fire door can be integrated with access control systems such as card entry and remote release.
