I've got a bunch of Dura-Blocks which are nice, but it means I have to stock 2.75" PSA strips, 1/4 sheet, 5" and 8" round (velcro and PSA), and belts for all the different tools. I'd love to get to something that cuts down on the variety in my shop.
I'm not home, one of the descriptions said 1/4 sheet but i believe its smaller. I'll check when i get home. It works well, the handle is a little short/close to pad but I still really like it.
