Accessory Clamp 1-3/4in w/ through hole

The Allstar Performance Accessory Clamp 1-3/4in with through hole (ALL 10490) is a precision-engineered aluminum roll bar accessory clamp designed for secure, repeatable mounting of auxiliary equipment on 1-3/4-inch outer diameter tubing. This clamp-on mount uses a 1/4-20 threaded connection paired with a 1/4-inch through hole, enabling builders and fabricators to attach auxiliary components—lights, switches, sensors, or custom brackets—to roll bars, cage work, and frame structures with minimal modification to the primary structure.

Constructed from natural aluminum, this accessory clamp offers a lightweight yet rigid solution for dynamic mounting applications. The 1/4-20 threaded mount accommodates standard fasteners and allows fine-tuning of accessory positioning during installation. The through hole provides dual-purpose functionality—serving as both a secondary mounting point and a cable pass-through for electrical harnesses or safety devices. Dimensions of 4 x 0.55 x 7.05 inches ensure compact integration without interfering with adjacent components, while the 0.13-pound weight minimizes load penalties on race vehicles or trail rigs.

This accessory clamp is widely used in motorsports fabrication—particularly in off-road racing, custom hot-rod builds, and safety cage installations—where reliable mounting of auxiliary systems is critical. Engineers and fabricators appreciate the flexibility of the threaded interface combined with the through-hole design, which allows multi-axis routing of harnesses while maintaining structural integrity. The aluminum construction resists corrosion in typical shop and garage environments, making it suitable for both street and competition applications.

Allstar Performance is recognized within the automotive fabrication industry for producing modular mounting solutions that simplify custom builds. The 1-3/4-inch clamp specification matches common roll bar tube diameters used in aftermarket cages and frame reinforcement kits, making this clamp a practical choice for builders standardizing their accessory attachment methods across multiple projects.
