We manufacture the following spare parts for our hinge models:
Left-handed (VK) (L)
Right-handed (OK) (R)
The durability of a spring depends on the temperature in which it is used, the degree to which the hinge is wound and how intensively it has been used. Also note that bending the hinge in the wrong direction may damage the spring. In many hinges, a damaged or worn spring can be replaced. To replace the spring, it is always necessary to first unwind the hinge and to take off the hinge or the door.
In some hinges, replacing the spring requires expertise and special tools. We recommend that you do not attempt to change the spring by yourself in any model except 001, 002, 003 or 004. For repair works such as spring replacement in other models, please contact our factory.
