This flexible rubber boot is 63 x 39x 39 mm with a 10 mm and a 25 mm opening.

It is surrounding the ballast rod on the wing root of the Discus b, Ventus-2 (SN < 561), Discus-2a and Discus-2b (SN< 234) which have been produced before June 2009. However, some of these gliders might have been retrofitted with the newer system. You can see on the suggested product the other bellow.

It is used for the ballast system of the Nimbus-3, -3D, -4 and -4D. For the Nimbus, the bellow may need to be adapted by cutting the larger end.

It is also used as a sealing around the brake line when crossing the wheel box in all single seaters.
