With the GURTFIX repair kit, you can repair and replace an old or worn roller belt without having to open the roller shutter box in a very short time. This GURTFIX repair set is designed for the Maxi roller shutter system and includes a sturdy roller belt with 23 mm width and 4.3 m length. The repair set consists of a belt strap, color-coordinated adhesive strips as well as a fixing set made of stainless steel and a practical mounting help. During installation, the new roll belt is firmly connected to the old roll-light belt about 10 cm below the belt guide. The worn roller shutter belt is then cut flush and the repair station is covered with the color-coordinated adhesive strip.Schellenberg Tip: To calculate the required length of the belt strap, simply multiply the height of your window or door by a factor of 2.5.This text is machine translated.
