Three shower screen parts are listed to suit Ideal™ screens, and all three are blocks: a pick-up block in black, the same pick-up block in white, and a set of three sill blocks in black. A range made up entirely of blocks tells you what actually fails on these screens. The sliding panel runs on nylon blocks rather than wheels, so once they wear the door drops, binds on the sill and eventually jumps its track, while nothing else in the assembly needs replacing nearly as often. Before ordering, pull one old block out and compare the overall size and the slot that grips the glass, since the same pattern is listed against Regency™, Showerite™, Norfe™ and BGC® screens and is identified by shape rather than by name. Colour is the other choice to make.
