Spring Box Units

Spring Box Units

Garador Mk3C C-Type spring box units were discontinued as a spare part by Garador in 2002, however thanks to the enterprising efforts of one of our suppliers, we are still able to supply “Pattern” units for all doors that were fitted with these units.

These pattern units have been carefully modelled from the original units and are available in all the sizes previously offered by Garador. Careful attention to detail means our pattern boxes normally locate exactly in line with the fixing points of the original box, helping towards a hassle free installation.

Mk3C / C-Type doors manufactured up to 1999, can be identified by the spring box unit mounted above the door which contains two springs connected to cables which run over pulley wheels at the top corners of the door frame and within the side tracks, down to the roller spindles which are mounted on the door panel around a third up from the bottom of the door. The unit should have a label attached with a part number such as PN108 on it, this is the number you will need to order a pattern replacement. If there is no label in existence please view or download a spring box unit compatibility chart here.

More recent Mk3C and C-Type doors have a spring box unit WITH a plastic cover whereas very early Mk3C doors had a spring box unit WITHOUT a plastic cover. The early Mk3C spring box units should be replaced in their entirety as changing the springs is both difficult and quite dangerous.

Garador Mk3C / C-Type canopy doors fitted with spring box units were discontinued in 1999 in favour of a new C-Type gear with side extension springs.
