Kitchen Chair Plastic Insert Measuring

Inserts are only measured by
of the pipe they go into

All inserts have a 1" spindle hole

**Wall thickness of your particular steel pipe may cause insert to not fit.

***We cannot guarantee all measurements will be correct for your particular pipe dimension or pipe wall thickness.

Inserts which do not fit despite correct measurement, can be made smaller with a file or grinding. Inserts that are tight can be boiled in hot water for several minutes to make more pliable.
