M10 Curved Disc Seat Post Washer (WASINDV1009)

Here's a unique item. The M10 curved disc seat post washer is used on the tubular round seat posts found on Jazzy and Jet Power chairs. A curved disc washer is "pre-bent" to fit perfectly on a 2" diameter seat post. Later power chair models usually used a quick release pin to secure the seat post to its pedestal, but even they can be retrofit with this washer and a 10-1.50x60 mm hex head bolt or machine screw.
