Description
A soft black rubber disc with a central hole, made to sit between the parts of a light fitting where metal would otherwise press straight onto metal. It measures 42mm across and 5mm thick, so there is a little body to it: press it and it gives, then comes back. The face is plain matt black, with no plating or lacquer to chip, and the edge is cut clean. They come five to a pack, which suits the way they get used, since these rarely go into a job singly.
Most of the work these do is quiet: cushioning a shade against a gallery, taking up a small gap in an assembly, spreading the pressure of a nut so a finish is not marked, or stopping a slight rattle in a pendant. They suit anyone putting a fitting together from parts or bringing an older lamp back into service, and they are handy to have in the drawer before you need them. We keep them alongside our lampholders and cable grips for exactly that reason.
The washer is rubber throughout, with a matt surface that takes a knock without showing it and stays flexible in use. Rubber dislikes oil and solvent, so wipe a dusty one with a dry cloth and put it back rather than reaching for cleaner; if one has gone hard or split, replace it rather than persevere. There is nothing electrical here, no flex and no contacts, and it is intended for dry indoor rooms. It carries a one year warranty. The same range runs to lampholders, converters, hook plates and cable grips, so a full pendant set can be put together from the same shelf.

Frequently Asked
What size is the washer?
Each one is 52mm long and 42mm wide, with a thickness of 5mm, so it sits neatly under a small gallery or nut without standing proud.
How many are in a pack?
Five, supplied together in a single pack.
What is it made from?
Rubber, in black right through, so there is no surface finish to wear off or flake.
Does it carry any current?
No. It is a non-electrical part with no contacts and no flex, used purely to cushion and pack out components within a fitting.
How should I clean it?
A dry cloth is enough. Keep oils, solvents and strong cleaners away from it, as they harden and perish rubber over time.
Is it suitable for outdoor lights?
We would keep it to dry indoor rooms rather than anything exposed to weather or damp.
