N track front mounted torsion spring system

The N track front mounted torsion spring system is on all heavier doors over 3048mm wide (10 feet) generally and will require good fixing points for the spring support brackets. It is available as an option on the single doors if required too.
The headroom required is 210mm above the door order height and 90mm each side for the vertical tracks and frame.

L track rear mounted low headroom system

The L track rear mounted low headroom torsion spring system is an option on the larger, heavier doors where headroom may be limited but be aware the horizontal track length is longer than the 2 options above.
The headroom required is only 115mm with a Hormann electric operator above the door ordering height and 90mm each side for the vertical tracks and frame.

H track high lift torsion spring system The H track high lift torsion spring system offers the horizontal tracks and spring at a higher level that can be specified from the factory. This system is rarely used unless you have very high ceilings and want the tracks out the way completely. It requires extra accessories for the electric operation and is generally 20% extra on the normal N track door prices.
Price and technical dimensions are all on application

All Hormann sectional doors are delivered in 2 packaged parts - the door panels and the gear and tracking operating mechanism.

If you need to know the exact weight for shipping purposes please email us the door design, model and size required and we will get the weight details for you.

A standard Hormann domestic sectional garage door will have all the necessary tracking, spacers, brackets and instructions for installation to a suitably prepared opening.

All you will require are the appropriate fixings to secure the framework and tracking to the structural opening of the garage. Unlike most other sectional doors the panels are factory predrilled for the very easiest on site assembly with a mistake in the assembly almost impossible.

Some consideration must be given to certain accessories if the opening is not exactly the correct size or installation is inbetween the opening:

hormann frame cover profiles for a sectional door frame legFrame Cover Profiles: Used to cloak the standard frame legs if any of the frame is likely to be seen from the outside. ALL Hormann fixing frame legs are powdercoated white as standard whatevercolour door is ordered and frame cover profiles ordered seperately will match the chosen door panel colour and finish.
They are available in 2 sizes depending how much of the frame is showing - 55mm and 90mm widths. If you are installing in between the opening be aware that the front of the frame legs are predrilled so you will require the 90mm covers to cloak these small holes.

Inbetween Installation Kit: If one or both of the frame legs is going to be installed inbetween the structural opening this kit gives you all the necessary bracketry to secure the frame leg at the 90 degree angle to the pier/wall. The standard legs are designed for installation behind the opening and have holes predrilled for this purpose.

Emergency Manual Release: A device to enable the operation of the standard emergency release of the electric operator from outside the door when there is no other means of access into the garage. There are 2 devices - one that connects to the handle if specified and another that connects via a key barrel in the top door panel when there is no handle option. We will ensure the correct parts are sent when ordered and they are the same price.

Insulated Fascia Sections: Not shown on our site as they are generally purpose made but you can have matching insulated fascia sections to infill above the sectional door if required and various options exist as to where this can be fitted.
