CURT Channel-Mount Adjustable Trailer Coupler 2-5/16 in Ball, 14,000 lb Capacity — Gloss Black, Dual-Bolt

CURT 25330 is a heavy‑duty, adjustable channel‑mount trailer coupler that secures a 2-5/16" hitch ball and supports up to 14,000 lbs gross trailer weight.

Built for trailers that need strength plus on‑the‑fly height adjustment, this cast steel coupler mounts to an adjustable eye channel and uses dual attachment bolts for added stability and reduced rattle. It features a user‑friendly latch that locks over a standard 2-5/16" trailer ball, a corrosion‑resistant gloss black powder coat, and a limited lifetime warranty from CURT.

How does this coupler let me level my trailer without welding or special tools?

The CURT 25330 is designed to mount on a vertical channel bracket, so you slide the coupler to the correct height and tighten two bolts to lock it in place. That adjustability eliminates the need to rework the trailer tongue or perform complex fabrication to get a level tow.

• Fits CURT channel systems (recommended models #48610 and #48650, sold separately)
• Vertical slide feature allows easy up/down positioning for precise tongue height
• Dual-bolt attachment prevents rotation and minimizes vibration

Will this coupler fit my trailer and standard hitch ball?

This coupler is machined to accept any standard 2-5/16" diameter trailer ball and is intended for heavy‑duty trailer use. The cast steel construction and engineered latch give a snug connection to the ball while matching typical mounting arrangements for channel‑style tongues.

• Designed to couple to 2-5/16" trailer balls (standard diameter)
• Works with a variety of heavy‑duty trailers that use an adjustable eye channel
• Latch is lockable to deter accidental opening and improve security

How strong and weather‑resistant is the CURT 25330?

CURT built this coupler from heavy‑duty cast steel and finished it in a gloss black powder coat to resist corrosion and road grime. Its load ratings are suitable for demanding towing while the finish and materials are chosen to withstand exposure to rain, salt, and dirt.

• Gross trailer weight capacity: 14,000 lbs
• Tongue weight capacity: 2,100 lbs
• Durable powder coat finish for long‑term corrosion resistance

How simple is operation and maintenance for everyday towing?

The coupler uses a straightforward latch mechanism that closes securely over the hitch ball and can be padlocked for peace of mind. Routine care is limited to keeping the latch and contact surfaces free of heavy rust, debris, and lubricating moving parts as needed.

• Easy‑lock latch for fast hookup and secure fit
• Padlockable design to add a theft‑deterrent when parked
• Minimal maintenance: inspect, clean, and lube latch yearly or after heavy exposure

Who is this for: The CURT 25330 adjustable channel coupler is aimed at owners and builders of heavy‑duty trailers who need flexibility in tongue height and a robust, long‑lasting connection to a 2-5/16" ball. It’s ideal for equipment trailers, livestock/construction trailers, or custom builds where the ability to fine‑tune hitch height and reduce rattle matters. Choose this coupler if you want cast‑steel strength, a secure latch, compatibility with CURT channel systems, and a factory powder coat finish backed by CURT’s limited lifetime warranty.
