Stegewop 5000 lb Class III Trailer Coupler for 2" Ball — 3" Channel Mount, Zinc-Plated Reinforced Steel

Stegewop's 5000 lb Class III heavy-duty trailer coupler securely mounts to 3" channel tongues and locks onto a standard 2" hitch ball for reliable towing under heavy loads.

This coupler is engineered for trailers that require more strength and a wider mounting surface than standard 2" couplers provide. Built from reinforced steel, finished with marine-grade zinc plating, and using a quick-lock latch, the unit balances durability with straightforward installation. It replaces narrower couplers on 3" square tongue frames and is designed to resist corrosion in wet or coastal environments while minimizing rattle and play on the hitch ball.

How does this coupler handle heavier loads?

The Stegewop coupler meets Class III standards with a maximum gross trailer weight rating of 5,000 lbs, giving you the capacity to tow larger utility trailers, campers, and boat trailers. Its reinforced steel construction and robust internal components are sized to keep deformation and wear to a minimum during repeated heavy use.

• 5,000 lb GTW rating suitable for many mid-weight trailers
• Reinforced steel body for improved strength and longevity
• Internal hardware sized for heavy-load durability and reduced flex

Will it fit my trailer's 3-inch channel tongue and 2-inch hitch ball?

This coupler is purpose-built for 3" wide square tongue tubes and is not intended for narrower 2" tongues. The socket is precision-molded for a standard 2" hitch ball, and the adjustability lets you fine-tune the grip to eliminate rattle and maintain a snug connection.

• Fits 3" wide channel or square tongue mounting surfaces
• Standard 2" ball socket for universal hitch compatibility
• Adjustable internal nut to tighten and reduce play on the ball

How does the coupler resist corrosion and outdoor wear?

Stegewop applies a heavy marine-grade zinc finish to protect the steel from moisture, salt, and road debris. That zinc barrier extends service life in wet conditions and is especially useful for boat trailers or winter towing where exposure to corrosive elements is common.

• Thick zinc plating for rust and corrosion resistance
• Suitable for freshwater and frequent wet-use environments
• Finish designed to withstand road grime and seasonal exposure

How easy is it to connect and secure the hitch ball?

The coupler uses a quick-lock latch with a high-tension spring and intuitive trigger, making hookups fast and consistent even in low light or cold conditions. The mechanism provides a positive lock and a tactile confirmation when engaged, while the adjustable nut allows you to fine-tune tension for the smoothest tow.

• Quick-lock latch for fast, repeatable hookups
• High-tension spring and trigger for a secure, audible lock
• Adjustable internal nut to eliminate rattle and optimize fit

Who this is for: This Stegewop 5000 lb Class III coupler is aimed at owners of mid-size trailers who need a wider 3" tongue attachment and a dependable 2" ball connection—think boat trailers, campers, and loaded utility trailers. It suits DIY trailer builders, fleet managers replacing worn couplers, and anyone who tows frequently in wet or corrosive environments and wants a rugged, adjustable, quick-locking solution.
