PLEASE MEASURE YOUR TABLE PRIOR TO ORDERING. These are 3" diameter and step down to 2 7/8". The corresponding hole in the table is 3" diameter (the recessed hole diameter) and steps down to 2 7/8" (the through hole).
These inserts have a 3" (77.5mm) outside diameter and have openings of 1 1/4", 1 7/8", and 2 1/8". The step diameter is approximately 2 7/8". They are 3/16" thick and have 3 snap tabs.
The color may be RED or YELLOW depending on our stock.
An example table is shown in the last photo. If your table does not look like this one it will likely not have a 3" recessed opening.
