Technical Data Sheets Sectional Doors

Our sectional garage doors use 2 technical bases: "single-rail" or "double-rail" guide rails.

Single-rail doors are quicker to install, but still require an operator.

The double track system is justified for high (over 2125mm) or non-motorized doors.

Mono-Rail System

→ Max. height 2125mm

→ Must be use with a garage door opener*

*the motor is needed to close the top panel.
Of course, in occasional use (e.g. power failure) you can still open the door manually.

What kind of lintel fallout do I need?

How do I determine the minimum lintel drop for a motorized sectional garage door? It's quite simple!

For a motorised sectional door, we recommend a minimum lintel drop of 150mm (the motor rail is thus placed 20mm above the top rail).

Example for a height of 2000mm under lintel you need at least 2150mm under ceiling.
