The door was installed with not too much difficulty. It’s definitely a procedure requiring 2 people. Excellent design. I had to concoct a drip guard on the inside at the bottom of the slider as water was dripping out onto the tub ledge when the door was closed.  try to install the slider as close to the inside wall of the tub so that water drips down into the tub (we did not want to use the included metal bar, for stopping the drip, as it could be a tripping hazard.). If cutting down the main support rod, make sure you cut the correct side (the slider door side) as one side must not be cut (as it is designed to hold the fixed/non-sliding glass door).
