The items I ordered, because I needed the triple partitioned white Plastering disc. This three-division white Plastering discs I could easily use. Therefore I have not complained. - But if the parts are completely required, there are problems: 1. Plastic mother is very firmly on the screw and can thus hardly turn. 2. The screw head is too much play in the slot of the bracket so that it is spinning when tightening the nut. Only craftsman with a talent for improvisation or hobbyists who know how to help themselves, can use the part useful.
(The photo is out of date, metal discs and metal nut are not supplied, but are not necessary).
