Accessory Clamp 1-3/8in w/ through hole

The ALLSTAR PERFORMANCE Accessory Clamp with 1-3/8-inch through hole and 1/4-20 thread mount (SKU ALL 10487) is a specialized roll bar accessory clamp engineered for secure mounting of auxiliary equipment onto 1-3/8-inch OD tube assemblies. Constructed from aluminum in natural finish, this clamp-on accessory provides a reliable fastening solution for race cars, off-road vehicles, and fabricated tube frame structures where space-efficient mounting is essential.

The clamp features a 1/4-inch through hole with 1/4-20 thread mount capability, allowing users to attach lights, cameras, brackets, or other accessories without welding or permanent modification to the roll bar structure. The aluminum construction offers a favorable strength-to-weight ratio critical in racing and performance applications where unsprung mass reduction directly impacts handling and acceleration. The natural finish provides a clean aesthetic while remaining receptive to custom finishing or protective coating if corrosion resistance is required in marine or high-humidity environments.

This accessory clamp is designed for builders and technicians who need flexible, non-permanent attachment methods for roll bar-mounted equipment. Common applications include securing onboard cameras for documentation, mounting auxiliary lighting, attaching hydraulic or pneumatic lines, or securing safety equipment. The clamp accommodates 1-3/8-inch tube diameter, a standard size in custom fabrication and motorsport applications. Weighing just 0.15 pounds, it adds minimal mass while delivering the mechanical rigidity required in high-vibration environments typical of racing and off-road use.
