The fitment kit is designed to easily help you determine what shaft size best fits your backing hardware. Each kit comes with a coupon for $5, hopefully making it free.

If you determine upon playing with the fitment kit you need a rare shaft smaller than 5/8 or something very unique to replace a glass knob, we will simply fabricate a new custom fitment tester and ship it out to you ASAP.
