Overview

The Fringe Sport Universal Mammoth Belt Squat System is a 900 lb capacity belt squat attachment for any rack — eliminates spinal load during squatting, fits all 3x3, 2x3, and 2x2 racks with 1" or 5/8" holes, and includes an adjustable padded belt.

Zero Spinal LoadTransfers weight from shoulders and spine to the hips — enabling deeper squats, heavier training, and pain-free leg work for athletes with back or shoulder limitations
Universal Rack CompatibilityFits every rack size on the market: 3x3, 2x3, and 2x2 with 1" or 5/8" holes — the most compatible belt squat attachment ever built
900 lb CapacityHandles serious strength athletes and high-volume commercial use — adjustable 39"–48.75" length covers all height ranges
Padded Adjustable Belt IncludedThree sets of D-rings provide a custom fit — the belt system ships complete and ready to use immediately

The Mammoth Belt Squat System brings the full benefit of a standalone belt squat machine to your existing rack. By anchoring weight to the hips rather than the shoulders and spine, the belt squat allows deeper squatting with heavier loads — particularly valuable for athletes managing back injuries, shoulder impingement, or limited upper-body mobility that makes barbell squatting painful.

Designed in collaboration with @KAIZENDIYGYM, the Mammoth is the most universally compatible belt squat attachment on the market. The 39"–48.75" adjustable length accommodates users of all heights. Use it for belt squats, lunges, calf raises, cable rows, and deadlift variations — the padded adjustable belt ships included.

Features

Everything that makes the Fringe Sport Universal Belt Squat System (Mammoth) stand out — built for athletes who won't settle for average equipment.

Zero Spinal Load SquattingTransfers the load from the barbell on your shoulders to a belt around your hips — enabling deeper squats, heavier training, and pain-free leg work without compressive spinal loading.
Universal Rack CompatibilityFits all 3x3, 2x3, and 2x2 racks with either 1" or 5/8" holes — the broadest compatibility of any belt squat attachment on the market.
900 lb Weight CapacityCommercial-grade capacity for serious strength athletes and high-frequency gym use.
Adjustable 39"–48.75" LengthCovers the full range of user heights — adjust to the exact length that positions the weight stack optimally for your height and squat depth.
Padded Adjustable Belt with 3 D-Ring SetsThe padded hip belt distributes load comfortably across the hip crests. Three sets of D-rings provide multiple attachment points for a custom fit across all body types.
Multi-Exercise VersatilityBelt squats, lunges, calf raises, Romanian deadlifts, cable rows, and shrugs — one attachment supports a full lower-body and accessory training program.
Deeper, Safer SquatsHip-loaded squatting encourages a more vertical torso and deeper range of motion — particularly valuable for athletes with mobility limitations or injury history.
1-Year Warranty1-year Fringe Sport warranty on the full system.
