Shower door roller and retainers

Another question-which is a bit unrelated - trying to replace a bottom retainer for the bottom of the door but not able to unscrew the damaged piece to be able to replace it. Any suggestions?
And lastly - The bottom retainers every so often slip out of the track. Any way to resolve this? Thank you so much, in advance, for answering all of my questions!
Thanks for any advice!



Hello there. For the 10-075, I believe you can use the guide for our 10-071 to remove and replace this hardware; the principles should be the same. See below. As far as your other parts, I am afraid we're not familiar. It's possible removing those screws at the top of the door might enable you to lift off the top track without completely dismantling the door, but I'm not certain, so take great care. As for the bottom guide, if there is a screw holding it on I would try using WD-40 Spray to loosen up the screw threads. You also might be able to cut the head off the screw with a hacksaw, or drill out the screw. No matter what you do take great care not to hit the glass.
