Online Lee Valley JessEm 10-Piece Insert Ring Set

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.
