What is the square shaft handle

Yesterday we mentioned that the multi-point lock handle is currently the most widely used handle system, and can also be subdivided into three types: A: U-fork handle, B：Square shaft handle, C: double-sided handle. And what we're going to talk about today is the square shaft handle.

The square shaft handle works like the U-fork handle, except that the position of the U-fork becomes the square shaft. You can see the pictures above. Because of the square shaft, it is named square shaft handle, and the working principle is basically the same as the U-fork handle. Rotating handle will match the drive lock to complete the locking and opening work. Similarly, we should pay attention to the following points when purchasing and installing:

1, The handle and the window profile should match each other.

2, Handle for specific models have a distinction between left handle or right handle.

3, Please make sure the length of the square shaft and the size of the square shaft (the size is usually 7*7mm).
