This is for a pair of white roller skate toe stops stoppers.
There are not metric so not for Roll-Line chassis/plates
These we think are imperial 5/8 inch thread.
These toe stops are universal aftermarket replacements that fit quad roller skates (double-row skates) equipped with adjustable toe stop plates.
Plate Type: Your skates must have an adjustable housing (where the toe stop screws directly into a large threaded hole on the plate and is locked in place using the included lock nut and washer).
Thread Standard: These utilize standard 5/8" imperial threads, which are the standard for most US and some UK quad skates.
Fixed/Bolt-On Plates: They will not fit entry-level skates (like classic Impala or standard Rio Roller skates) that use a narrow 5/16" non-adjustable bolt running through the center of the stopper.
Note/ Metric Plates: They will not fit European-threaded plates (such as Roll-Line) which require metric stems.

Please note I do try my best to ensure my write ups accurate and correct as I can but just occasionally I might miss or get something a little wrong. So I always as please check out my photos for all information you need.
If in any doubt please check out my feedback.
Please also bear in mind eBay set postage costs here not me working on simple delivery and size and weight of item so I don’t make anything from it even though it costs me for packaging materials.
Many thanks for looking
