The door slides on a track. When the door is fully closed a pin drops down, automatically latching the door in place. To open, lift the door handle near the centre of the tub and slide the door open. This is easier from inside of the bathtub. For those who can’t reach over the side of the tub, there is an extender bar available.
The door has an internal stainless steel frame with bronze pivots and Delron wheels. The aluminum track is hard anodized for durability. The top wheel is spring loaded so the entire door can be removed to reach the access panel behind (in case of installation or maintenance).
