Overhead Door Closers
Overhead door closer:GEZE offers door closer systems for any type of door with a range of individual setting options. From the smallest overhead door closer to the multi-faceted variations for use with fire and smoke protection doors: The door closer ranges with link arm or guide rails offer a range of combination options to meet every requirement.

The door systems with the “free swing” function are ideal for doors that need to be operated with very little physical force and yet still provide a high level of security, for example, in hospitals, care institutions, homes for disabled people or schools.
Overhead door closers with link arm for double leaf doors
The double-leaf door closer systems of the IS series with integrated hydraulic closing sequence control are approved for installation on fire and smoke-proof doors. The integrated closing sequence control with protection against intentional damage ensures the correct closing sequence of both doors for double-leaf doors.
When the door is closed, the active leaf remains in waiting position until the fixed leaf is closed and releases the active leaf via the closing sequence control. The closing force according to EN 1154 with optical size indicator and closing speed can be set from the front. The end stop setting is made using the link arm.
Overhead door closers with guide rail for single leaf doors
Door closer for single leaf doors with guide rails represent modern closing technology at every door. The wide range of GEZE door closer technologies ensures that there is a technical solution for every requirement, for example, with electromechanical hold-open device, with a smoke switch control unit or with a “free swing” function.
overhead door closers with a guide rail for double-leaf doors
Closing systems with a variety of specific adjustment options also provide solutions for double-leaf doors with GEZE door closers and the associated guide rails of the ISM series, i.e. with integrated mechanical closing sequence control. A variety of versions, e.g. with an electromechanical hold-open device, with a smoke switch control unit, with a comfort hold-open function and a “free swing” function, satisfy almost every requirement and are tested in accordance with the relevant standards (EN 1154, 1155, 1158). GEZE hold-open systems are approved by the German Centre of Competence for Construction (DIBt).
The GEZE guide rail range for free swing door closers
In the case of system solutions with the GEZE free swing door closers, users benefit from the particularly adaptable range of guide rails for double-leaf systems. In order to make the application options on double-leaf systems even more flexible, the hold-open or free swing lever is already delivered with the door closer. The optimised range of rails allows the user to map out even more combinations and equip doors with a GEZE hold-open system according to the respective area of application.
Due to the following additional guide rails, all the possible combinations listed in the general official building approval can be mapped out:
E-ISM/S guide rail – guide rail with integrated closing sequence control and electrical hold-open device on the passive leaf: for combinations with free swing function on the active leaf or hold-open magnet on the active leaf
R-ISM/0 guide rail – guide rail with integrated closing sequence control and smoke switch control unit: for combinations with free swing door closer and/or hold-open magnet on the active leaf and hold-open magnet optionally on the passive leaf
R-ISM/S guide rail – guide rail with integrated closing sequence control, electrical hold-open device on the passive leaf, smoke switch control unit and for combinations on the active leaf or hold-open magnet on the active leaf.
