This heavy-duty stainless steel attachment is designed as a versatile mounting point for power racks, supporting up to 1000 lbs. Compatible with both 2"x2" and 3"x3" rack uprights (5/8" or 1" holes), it serves multiple functions: connecting pulley hooks for cable systems, hanging training accessories, or acting as a secure anchor point for bands/straps. The 304 stainless steel construction ensures corrosion resistance, while protective plastic inserts prevent rack damage during installation. With tool-free setup via screw-locking pin, this industrial-strength connector transforms your squat rack into a multifunctional training station for strength, mobility, and rehabilitation exercises.
