When replacing the lift-and-slide door fitting, the running wheels and the complete lift-and-slide lock must be replaced. The new lock has a different transmission (ball) than the old lift-and-slide lock (hole).

The old running wheels do not fit in the new system. The old series GU 935 and GU 936 are replaced by the new series GU 934 and GU 937.

For a sliding door hardware, you can choose between a single or double handle. Furthermore, it is important whether you want to secure the sliding door from the inside and/or outside. There are various colors of sliding door handles available. Over time, certain parts such as wheels or handles may show wear and tear. This is a normal process, especially with intensive use. However, it is important to replace these parts in a timely manner to prevent your sliding door from functioning less effectively. At Van Doorn Openingstechnieken, you will find replacement parts that are compatible with most standard sliding doors.
