Manhattan Spherical quadrant shower enclosure

[Bayardmm]

several years ago we had a Manhattan Quadrant Sphere shower enclosure installed and it has been superb. However, recently the door, when closing, has started to jump off the track, top and bottom. I’ve checked the track rail, and it’s mountings at either end are as tight as I could get them without solving the problem. On closer inspection I’ve noticed that the rail drops slightly, 1-2mm, as the door leaves the fixed panel section towards the open section. If I support the open section, with minimal effort, I cannot reproduce the problem. I can do this easily but my wife can’t. Does anyone have a solution. I’m loathed to replace the enclosure as all the other features, floor, walls etc are geared to this enclosure.

Are the rollers worn

They seem ok, made sure the grooves are clean.

So it's the metal runner bar along the top that connects the side sections that's drooping? If so then not a lot could be done to stop that I wouldn't think. Unusual for the bar to weaken over the time though, I would think it's probably more to do with the actual rollers getting old rather than the bar.

I would check out the warranty though if it's Manhattan, as they usually have long guarantees

Too old, plus they’re no longer in business, although you can still get some spares.

Can you adjust the upper rollers to drop the door slightly. Other than that I would guess the springs in the lower ones have weakened and need replacing

I’ve recently replaced one of the lower clips, as it broke during a derailment. It’s only the leading edge roller that’s affected. I was thinking the opposite of your suggestion and was wondering if I could adjust the upper roller assemblies to lift the door and therefore reduce the amount of play at the bottom. The lower clips have a lug on them which is situated under the glass door edge, and therefore cannot have their position altered. When the door derails it starts with the lower clips releasing the door which then swings slightly, like a plumb line, away from the tracks causing the roller to derail.
