BIG Savings !
These were the exact furnace blocks offered by my furnace retailer, and were less than 1/2 the price. The independent installer I used said he will now shop at SupplyHouse for these.

not as described
these r described to have "rubber feet" there's no rubber to be found on these things. just a sticky pad for the furnace to sit on but is all plastic on the rest of it. get the rubber squares

Easy to use
Blocks are easy to place under corners and have sticky paper to keep in place. Keep furnace off the floor to get air circulation underneath to prevent moisture from creating rust on the bottom of the furnace. Used these numerous times.

much lighter than cement blocks
I guess I am getting old, but this is way better than using cement blocks as furnace base.

Works great
Nice alternative to bricks. Looks cleaner and won't absorb moisture like blocks/bricks. Seems well made.

Good furnace support
The like these because they keep the furnace up off the concrete so the bottoms won't rust out. Good price as well. My only complaint is the sticky could be a little more

I would buy this product
it works great if you need to raise equipment, and it makes it look good also. The sticky pad works great, no slip or slide.

Great Product Beats Pump Ups
These are a great affordable product that does the job!
You can't beat the price here and they keep the furnace / duct out of the pan.
