CURT 49120 12" Receiver Tube 2" x 2" Raw Steel — Weld-On, Reinforced Collar

CURT 49120 is a 12-inch, 2" x 2" raw steel receiver tube built for welding into custom towing and fabrication projects.

This weld-on receiver tube from CURT supplies a solid, no-frills building block for custom hitches, extensions, and workshop fabrications. Made from heavy-gauge steel and finished raw for immediate welding, the 49120 lets you tailor length, orientation, and mounting to your project while accepting standard 2" x 2" shank accessories.

What are the main features and materials used in this receiver tube?

The 49120 is constructed from quality solid steel with a raw finish so it can be welded directly into place. It includes a 1/2" reinforcing collar at the mouth and a factory pre-drilled pin hole to speed installation.

• 2" x 2" internal opening to accept standard shanks, ball mounts, and accessories
• 12" overall length for added reach or fabrication flexibility
• 1/2" reinforcement collar to strengthen the visible opening
• Raw steel finish designed for welding and custom mounting
• Pre-drilled hole sized for standard hitch pins

How does this receiver tube fit with existing hitch accessories?

Because the internal dimensions follow industry standards, the CURT 49120 works with virtually any 2" x 2" shank accessory. You can slide in ball mounts, hooks, adapters, or other receiver-mounted gear and secure them with a standard pin.

• Compatible with 2" shank ball mounts and step clips
• Accepts standard hitch pins and clips through the pre-drilled hole
• Works as an extension or as part of a custom welded assembly

Can I weld this tube into a custom towing setup safely?

The unit is supplied with a raw steel surface specifically so it can be welded, but safe structural welding depends on proper technique and planning. Ensure welds meet load requirements and consult structural or towing specifications for your application.

• Raw finish ensures clean weld penetration and strong joints
• Reinforced collar reduces stress at the receiver opening
• Use appropriate welding method and qualified fab work for towing loads

What dimensions and prep steps should I expect before installing?

The tube measures 12 inches long with a 2" x 2" internal opening and includes a 1/2" collar and pre-drilled pin hole. Prep typically includes cleaning, fitting, tack-welding, final welding, and applying corrosion protection if the assembly will see the elements.

• Overall length: 12"; internal opening: 2" x 2"
• Check alignment and fit before final welding—tack in multiple spots
• Finish welds, then coat or paint to prevent rust for outdoor use
