3" Aluminum Rigid Back Up Pad 5/8-11 Thread
It is so difficult for fabricators to find a really good quality aluminum back up pad. Weha has found a great quality Aluminum Back Up Pad that is super solid, perfectly flat, premium hook and loop, and a glue that holds the velcro on even when used dry and the heat builds (which is usually where other aluminum back up pads fail).
