FURNACE LIFT BOX – FURNACE SUPPORT BOX

Reve Porter Furnace Lift Boxes (FLB) are designed to fit under a standard-width furnace in upflow applications to allow for more return air or to raise the furnace. The box depth is 25”, measured front to back, and comes in several width and height options. Our Furnace Support Box (FSB) is 28” deep to allow the entire furnace to sit on the box with no overhang.

Custom sizes are also available.
