Determining the handing of a sliding door is an important step in the installation process, as it ensures that the door will open and close correctly. Here is a step-by-step guide on how to determine the handing of a sliding door:

1. Stand on the outside of the door and look at the hinges. If the hinges are on the left side of the door, the door is a left-hand sliding door. If the hinges are on the right side, the door is a right-hand sliding door.
2. If the door has a lock, determine which side the lock is on. If the lock is on the left side of the door, the door is a left-hand sliding door. If the lock is on the right side, the door is a right-hand sliding door.
3. If the door does not have hinges or a lock, determine which side the door handle is on. If the handle is on the left side of the door, the door is a left-hand sliding door. If the handle is on the right side, the door is a right-hand sliding door.
4. If the door has a latch or lock on the top and bottom of the door, it is a center-hung sliding door.

What is the most common sliding door handing?

The most common type of sliding door is the hinged door. This type of door is usually made out of a single piece of wood that has been cut into two pieces. One side has a handle, and the other side has a lock. The hinges are usually on one end, and the lock is on the other end.

It is important to note that the handing of a sliding door can also be referred to as the “handing” or “swing” of the door. It is important to accurately determine the handing of a sliding door before installing it, as an improperly installed door may not open or close properly.
