Unmatched Durability and Performance
The foundation of the 4GMSXB rack is its heavy-gauge steel construction. The strong, 1-5/8” square steel crossbars are designed to handle substantial loads, boasting an impressive capacity of 500 lbs when weight is evenly distributed. To ensure longevity and protect against the harshest weather conditions, every component is treated with a zinc primer and finished with a thick, marine-grade white powder coat. This dual-layer protection resists chipping, scratching, and corrosion, keeping your investment looking professional for years to come. The uprights are engineered not just for strength but also for convenience, featuring accessible tie-down points that make securing your cargo quick and easy. With the 4GMSXB, you can drive with confidence, knowing your equipment is safely anchored to one of the toughest van racks on the market.
