I plan on purchasing this door. How do I contact the manufacturer regarding what I would need in the walls to support this sliding frame less shower door while the walls are off? I am also concerned about exploding doors which happen at times while in the shower.  I do not remember hearing about this with a framed shower door which is what I have had. All I do know at this point is the door looks great. I am concerned about water coming out of the  bottom of the door and between the doors and at both ends. My previous door had a track on both ends that the door went into. I have not gone out since the virus and have not actually seen the door but picture looks great. Do wish it had the water repellent on it though. Still afraid is it worth taking a chance in getting cut with a frame less door for the looks. IT IS A BEAUTIFUL DOOR. I am giving it a 5n star for the looks only can't say anything else, I do not know? Can anyone give me info. thanks
