Manticore Squat Stand Builder (3" x 3", 1" Holes)

Compatible with non-flat-foot Manticore power racks, our flat foot support system includes flat feet, reinforcement plates, and hardware to hold everything together.

The flat feet come in 54" and 63" lengths, with an optional 43" flat foot crossmember to connect them for added stability.

The 54" length can be paired with the 24" and 30" crossmember depths, while the 63" length can be paired with the 24", 30" and 43" depths.

You can select the flat foot with a bottom cross member that connects the 2 feet for increased stability, or leave it out. However, the bottom cross member is NOT compatible with the lat pulldown attachment - you'll need a rear base stabilizer instead.

Popular combos are:

• 43" with a 63" flat foot for maximum roominess.
• 30" with the 54" flat foot for maximum stability and minimal space.
• Or get a little weird with the 24" depth and 54" flat foot.

IMPORTANT: The flat foot support system adds 3-1/4" to the overall height of your rack. Compatible with non-Flat Foot Manticore power racks only.
