This is a medium density pad with heavy duty hook and loop back that fits our sanding strips perfectly.
We have two kinds: One has enough flex to twist and turn on spindles, and works on a flat surface as well.
The other Backer Pad is rigid with no flex.
They both have a comfortable grip that feels good in the hand and should minimize fatigue.2.75″ wide and 7.75″ long with a flat hook and loop surface.
