CURT Multi Ball Mount 2in & 2-5/16in for 2x2 Receiver — Welded, Gloss Black, Anti-Rattle Ready

The CURT 45002 Multi Ball Mount is a welded, hollow-shank hitch accessory with both 2" and 2-5/16" trailer balls for fast switching between coupler sizes.

Switching trailers shouldn’t mean swapping whole ball mounts every time. The CURT 45002 bundles two commonly used tow ball sizes onto a single straight shank that inserts into a standard 2" x 2" receiver. Built with permanently welded balls and a gloss black powder coat, it’s designed to simplify matching different couplers while maintaining a low-profile, theft-resistant setup that accepts an anti-rattle insert.

How does this multi ball mount make towing multiple trailers easier?

Instead of carrying and installing separate ball mounts for each coupler, the CURT 45002 gives you two fixed ball sizes on one shank. You simply choose the correct ball for your trailer’s coupler and hitch up—no tools or separate mounts required. The welded attachment prevents ball rotation or loosening during use.

• Two integrated balls: 2" and 2-5/16" for common coupler sizes
• Quick selection: pick the correct ball and connect without swapping mounts
• Welded design: permanently attached for security and stability

What towing capacities and tongue weights are supported?

This dual-ball mount provides different capacity ratings depending on which ball you use. The 2" ball handles medium-duty loads while the larger 2-5/16" ball is sized for heavier trailers. Always match the ball and hitch rating to your trailer’s Gross Trailer Weight and tongue weight for safe towing.

• 2" ball rated for medium-duty trailer loads
• 2-5/16" ball rated for heavier towing needs
• Check vehicle and trailer ratings before towing

Will this mount fit my vehicle and reduce hitch rattle?

The CURT 45002 is built for a 2" x 2" receiver tube opening, the most common receiver size on trucks, SUVs and many full-size crossovers. Its hollow shank accepts an anti-rattle kit or insert to help minimize movement between mount and receiver once installed. The gloss black powder coat helps resist corrosion for long-term use.

• Designed for 2" x 2" receiver tubes
• Hollow shank accepts anti-rattle hardware
• Durable powder coat finish for weather resistance

How secure and theft-resistant is the multi-ball design?

Both trailer balls are permanently welded to the shank so they cannot be unscrewed or removed without cutting. That limits the opportunity for casual theft and ensures the balls remain tight over time. For added security, use a receiver lock through the hitch pin and consider vehicle-specific anti-theft devices.

• Permanently welded balls eliminate loosening risk
• Permanently attached design reduces theft potential
• Compatible with standard hitch pins and receiver locks

Who is this for: The CURT 45002 is aimed at frequent tow vehicle owners who connect different trailers—such as utility trailers, boat trailers, and campers—and need a simple, durable way to accommodate varying coupler sizes without swapping mounts. If your vehicle has a 2" receiver and you want a ready-to-use, reliable towing solution that accepts anti-rattle hardware, this multi-ball mount provides convenient compatibility and robust construction.
