21" Adjustable Flexible Sander is rated 4.375 out of 5 by 8.
Rated 5 out of 5 by from Good for curves I've got 2 of the flexible sanders. This 21 inch and a shorter one. Keep in mind where you will be using it. I find I'm using the shorter one most of the time, but on those real long large curved panels the 21 is the only way to fly.

Rated 5 out of 5 by from Excellent Works very well with dynagrip sand paper. Would not stick to klingspor paper. Easy to use to shape large fenders. Started with just one sander to test out but plan to buy additional sizes.

About 21" Adjustable Flexible Sander

Straight, smooth, ripple-free finishes start with perfectly straight bodywork and accurate block sanding.

Remove any of the 3 steel rods inside the urethane foam body to adjust the flexibility of the sander.


21"-long Flexible Sander


Type "PSA sandpaper roll" in the "Search Our Site" box at left to shop our complete selection of sandpapers.


Great for sanding curved surfaces like hoods, roofs and fenders on earlier cars. Sand body panels from flat to curved. Sander is extremely flexible without rods. As the number of rods increases, so does the stiffness of the sander.
