CURT 2.5" Receiver Tube 10" Long (Raw Steel) — 2.5" x 2.5" Weld-Ready with 1/2" Reinforcing Collar

CURT 49510 is a 2.5" x 2.5" x 10" raw steel receiver tube built for welding into custom towing solutions and receiver extensions.

This raw receiver tube from CURT provides a heavy-duty, weld-ready building block for fabricators, mechanics and DIYers who need a reliable 2.5" receiver opening. Made from solid steel with a 1/2" reinforcing collar and a pre-drilled pin hole, the unit arrives unfinished so it can be welded, coated or integrated directly into custom hitch assemblies, trailer frames or fabricated recovery points.

How does this receiver tube fit standard hitch accessories?

The 49510 is sized to accept the common 2.5" x 2.5" shank used by larger ball mounts, pintle or hook adapters and many heavy-duty accessories. Its internal dimensions follow industry practice so compatible items slide in and secure with a standard pin.

• Accepts 2.5" x 2.5" shanks including ball mounts and tow hooks
• Pre-drilled pin hole for conventional hitch pins or lockable pins
• Works as an extension or replacement when welded into place

What makes this tube durable for towing fabrication projects?

Durability comes from its solid steel construction and the 1/2" reinforcement collar around the mouth, which reduces deformation where loads concentrate. The raw finish allows welds to bond directly to clean steel for a strong fabricated joint.

• Constructed from solid steel for maximum structural strength
• 1/2" reinforcing collar strengthens the receiver opening
• Raw steel finish enables high-quality welds and custom coatings

How do I use the 10" length in custom installations?

The 10" overall length gives fabricators room to position the receiver for proper clearance, setback and alignment with vehicle frames or trailer tongues. It can serve as a short extension, a spacer inside a fabricated bumper, or the finished receiver when welded into place.

• 10" overall length for clearance and positioning flexibility
• Can be welded as an exposed receiver or used internally as a sleeve
• Suitable for custom bumpers, winch mounts, and tow bar attachments

What preparations or accessories are recommended before welding?

Prepare the mating surfaces by removing coatings, rust or contaminants to ensure clean welds and durable bonds. Consider protective finishes after welding, and select pins, clips or locks rated for your towing loads.

• Grind or sand weld areas to bright steel before welding
• Use corrosion-resistant finishes after fabrication (paint, powder coat, or plating)
• Pair with rated hitch pins, bolts or retaining hardware appropriate for load

Who this is for: CURT 49510 is aimed at experienced welders, professional fabricators and knowledgeable DIYers who build or modify towing equipment. If you need a standardized 2.5" receiver opening in a raw, weld-ready form—whether for custom bumpers, trailer builds, recovery rigs or extension pieces—this tube provides the reinforced, high-strength base to integrate into your project.
