These glass-filled polycarbonate flush insert rings securely lock into the 3 7/8” opening of any JessEm router lift or table, with an easy 1/4 turn. Each ring is labelled with its aperture size so you can easily match the insert to the bit size you are using. The set includes inserts with center holes of 1/4", 3/8", 1/2", 3/4", 1", 1 1/4", 1 1/2", 1 3/4", 2 1/4" and one blank for making a zero-clearance insert.
The storage caddy lets you keep rings conveniently organized to quickly find the size of insert you need, and holds a total of 14 rings so you have space for additional blanks (sold separately) if required.
