4" DAMO Super-Flex Back Holder/Backer Pads for diamond polishing pads

This holder works great for polishing concave and curved areas! I used it to polish the inside of a concrete sink and never had trouble with pads flying off even at high speeds. You do have to squeeze the pads to the holder well to engage the velcro. Damo has made a good product. NO sign of wear after one counter polishing venture.

Works great; well balanced, smooth, flexible. I've used several types of backer pads; this may be the best I've ever had.

Works perfect on "out side" curves.Good quality product. I like it a lot

This unit is more flexible than normal backer pads so it allows you to conform to the curved edges of a counter, etc much more easily without digging in.

Used for about 10 minutes then rubber separated from attaching nut. Have used other brands in similar situations for many hours. Very disappointed with product.

Is not super flex. I bought it that said it was superflex. but it is not the same .. I get it for half the price I paid.

There are cheaper ones out there- and that's what you get- cheap. These are amazing and really saved my project.

They are no where near as flexible as the name implies. I had to heavily modify the ones I bought to do the job I wanted them for. I ended up cutting a large quantity of the rubber backer off in order to allow my diamond polishing pads to flex the amount required to polish the concrete I was working on. I basically reshaped it to a 3/16" thick pad except where the brass mount is.
