The low headroom system has been specially developed for installation situations with minimal headroom. It allows you to install high-quality industrial sectional doors in even the lowest installation situations. This version has a rear-mounted spring system, suitable for a minimum installation space of 200 mm. The system’s maximum drive-through height can be achieved with a headroom of 240mm or more.

This special top roller carrier has been developed for the LHI system. The top roller carrier ensures that the system can open and close easily, with a minimum headroom of 200 mm. The system’s maximum drive-through height can be achieved with a headroom of 240mm or more.
If there is more than 300 mm of headroom available, then this system can be installed with a regular top roller carrier. This option is more economical compared with the 200 mm top roller carrier.
In the LHI system, the spring bumper is easy to fit under the tracks.
Use the alignment profiles to align the sectional door to the mounting surface. It is not necessary to measure crosswise.
The high flanged mounting angle positions the door leaf approximately 20 mm from the installation area for easy access to the double slotted holes. The side sealing weather strips guarantee the best door parameters, such as U-value, air and water permeability.
Our universal operator support bracket ensures a direct connection between the operator and the bearing plates. This support bracket is universal, and is suitable for SOMMER, GFA, Marantec and MFZ-Ovitor operators.
The raised track edges prevent the rollers from slipping out of the track. Lateral forces are absorbed by the safety device, especially when closing the door in a curved section.
DOCO's spring breakage devices have been developed and tested, using a reliable and safe design.
Use the c-profile as a spacer for the vertical tracks. This makes installation more accurate, faster and easier. The result is a sectional door that opens and closes perfectly.
Choose flat or curved connections.
In situations with a sloping roof, it is better to have your door system run at the same angle as the roof. This makes optimal use of the available space.
The horizontal and vertical track sets are custom made and checked by DOCO before they are despachted. The torsion springs are pre-assembled, and can be attached to the power unit as required, together with the spring break device, cable drum and brackets. After the final inspection, all industrial sets are wrapped in plastic for extra protection during transport so that they can be stacked.
We offer profiles and seals that can be used to build full vision doors. The range currently contains panel specific top and bottom profiles. These are used in combination with pre-milled side and intermediate profiles (for 500 and 610 mm panels) to create the full vision panel frame. Depending on the snap-on profile you choose you can use either single or double glazing. Three types of seals keep the wind out and the warmth inside. These full vision panels can be used in combination with regular panels.
