Swivel Chair Replacement Parts

What's this about?

Some office chairs have the back rest attached to underneath the seat bottom using a curved piece of steel with 2-3 bolts.

Style #3318 has the 2 holes predrilled.
If purchasing stye #3323, the holes are not predrilled.

You will not have to drill these holes if the chair back is attached to the seat.

To drill these 2 holes, trace the hole location from the old mechanism and drill the same size hole.

We suggest when drilling and for safety, to place a 3/4" thick wood board under the mechanism for when the drill point goes through the metal. It will grab & twist! Drill slowly and a few drops of oil while drilling is good.
