Technical Details and Measurements for Hormann LPU42 Sectional Doors
Z Track Application
Z tracks (tension springs) are supplied as standard on all LPU 42 sectional doors up to 13 feet wide (4000mm). Over 13 feet wide (4000mm) the N tracks are supplied as standard with the low headroom (L track) available as an option.
N Track Application
N tracks are supplied as standard on all doors over 13 feet wide (4000mm) and the L track (Low Headroom) version is an option if headroom is restricted. N tracks can be ordered on doors less than 13 feet wide (4000mm) if required.
L Track Application
The L track (Low Headroom) option is available where internal headroom is restricted. It is also worth noting the requirements for a structural fixing point is moved to the rear of the tracks instead of the front position for the N tracks.
H Track Application
H tracks (High Lift) are useful when you have a high internal ceiling and require the door panels and tracking to be out of the way when the door is open.
Sideroom
The diagram above shows the frame leg dimensions required for the Hormann sectional door and the required depth to accomodate the entire mechanism including wheels, etc.
When installing inbetween a structural opening we recommend adding 10mm each side and purchasing the inbetween installation kit as well as frame cover profiles in order to cloak the front face of the frame legs as for every colour of door ordered the legs are always white and also are predrilled with holes for a behind brickwork opening installation.
