Steel Thrust Washer Manual

Style # SKU 84
Hardened steel thrust washer.
$9.45 each

Keeps chair from changing height during use

Installs underneath the Bell. 
Some POSTS do not have a groove machined into them preventing installation (do not attempt post removal). To install SKU 84, hacksaw cut one edge best as possible and bend one edge to provide enough space to force onto the post  into the machined groove. The users and chair's weight will serve to flatten the SKU 84 while in use.
