DiversiTech FB-1 Furnace Mounting Block

keeps the furnace from setting on the concrete floor and rusting, Self adhesive. I still ran a self piercing screw them the though. Excelent product. Where were they 30 years ago? beats wood or concrete blocks by a long shot.

Looks promising but haven't installed yet.

One of the pads was missing. I didn't need it, but someone else might.
