Method

With regards to these installation instructions we are referring to stacker doors with two sliding doors and one fixed panel.

There are many different examples of stacker doors such as centre opening with two doors interlocking to the left and two doors interlocking to the right. There are also examples of three sliding stackers, one active and two non active all sliding two one side. This combination can also be a centre opening, meaning six doors in total and is quite rare. Each individual door or doors in the centre opening situation will have to have their own full length tracks. If they do not exist then they will have to be installed.

Receiving interlocks must be present on the fixed glass panels; these serve two purposes. Firstly to locate the door precisely in the locked position and secondly to lock the doors together.

For installation where existing tracks are present use following steps:

Step 1: Place the non-active door on the inside track and using bottom rollers only, adjust to line up the back of the door with the receiving interlock on the fixed glass panel. If there is no receiving interlock adjust to line up the back of the door with the glass side of the fixed glass panel. Ensure the door is perfectly square and parallel.

Step 2: Place the active door onto the outside track and using bottom rollers only and adjust to line up parallel with the closing channel.

Step 3: If no receiving interlock is present on the fixed glass panel then install before proceeding. Install the frame interlock to the back of the non-active door using 5 x 5/32 rivets. Roll the door back and forth to make sure that frame interlock is connecting with fixed glass panel receiving interlock cleanly.

Step 4: Install the lock on the active door to the closing channel, slide the active door into the closed position and check the lock.

Step 5: Place the active door in the locked position. Place the non-active door in the closed position with the frame interlock connecting with the receiving interlock on the fixed glass panel. This should now align the internal non-active door frame with the back of the active door frame; they should line up one behind the other.

Step 6: Make a vertical mark on the non-active door frame both top and bottom to indicate the back of the active door where the frame interlock will be installed. Slide back the non-active door and install the receiving interlock to the face of the non-active door where marks are indicated.

Step 7: Return the doors to closed position and install the frame interlock to the back of the active door. Open the active door, it should connect with the non-active door and push both doors into the fully open position. Now slide the active door into the closed position which should effectively interlock with the non-active door pulling both doors into the closed position. All doors should interlock with the active door locking into the closing channel and the non-active door locking into the fixed glass panel.

Step 8: Once the locking mechanism is functioning correctly go inside and adjust the top rollers to take any up-and-down movement out of the doors. Slide doors to the fully open position and then into the closed position several times to ensure proper function.
