CTW 4″ 16″ Offset Hinges For Trailer and RV Doors

These 16″ offset strap hinges are designed for trailer and RV doors, offering extra clearance with a 5/16″ pivot point. The non-removable hinge pin and 3-1/4″ mounting hole spacing help streamline retrofit projects. They’re ideal for trailers or RV compartments where hinge clearance is tight and corrosion resistance is important thanks to zinc coating. Best for owners replacing door hinges with a need for reliable adjustment and long service life. A single hinge set is suitable for one door, while paired units support double-door configurations.
Best for: owners upgrading a trailer or RV door that requires extra clearance and a robust, corrosion-resistant hinge. Choose this if you need non-removable pins for a secure, maintenance-light installation and you’re replacing worn strap hinges on long-entry doors.
Limitation: installation requires precise alignment; incorrect spacing can affect door swing. Ensure center-to-center hole spacing matches your mounting pattern before drilling.
Hedday Weld On Trailer Hinges Heavy Duty, 4 Pack

This 4-pack is built for heavy-duty needs, including dump trailer doors, gate bodies, and horse trailers. Each hinge features a grease fitting to ease lubrication during frequent use, supporting smoother operation over time. The black-painted steel construction provides surface protection against daily wear and outdoor exposure. Best for: heavy-traffic doors that benefit from regular lubrication and a rust-preventive finish. It’s a strong choice for retrofit projects where daily opening and closing are expected.
Better for: applications demanding greasable pivots and weld-on installation. Avoid if you need a lighter-duty hinge or a non-greaseable option for a quick, bolt-on repair (this set is welded-on only).
Caution: surface paint can wear over time; monitor for signs of corrosion in harsh environments and re-lubricate per use cycles.
SPARKWHIZ Weld On Trailer Ramp Hinge 10″ Kit

Designed for ramp doors or heavy-duty hinge needs, this 10″ long hinge set is a practical choice for ramp gates and similar applications. The kit emphasizes a robust steel composition with corrosion resistance, suitable for outdoor trailer use. Best for: ramps on trailers and trucks that require strong hinge leaves with a wide range of motion. Choose this if you need a reliable greased option that handles frequent opening and closing.
Limitation: this kit fits a specific ramp width and may require custom alignment for non-standard trailer dimensions. Ensure your ramp’s hinge plate dimensions align with the kit’s specs before welding.
CTW 16″ Strap Hinges, Pair for Trailer and RV Doors

This pairing provides two 16″ offset bent strap hinges designed to handle trailer and RV doors needing extra clearance. The 5/16″ corner clearance is achieved through an offset bent design, with non-removable hinge pins for secure operation. The zinc coating adds corrosion resistance, supporting longer life in outdoor environments. Best for: replacing worn-out hinges on long entry doors where clearance is critical and a non-removable pin is preferred for security.
Better for: installations where precise hinge-to-door alignment is established and you want a straightforward replacement without extra hardware. Avoid if you require a bolt-on hinge kit that doesn’t require welding or permanent pin removal.
Coloch 4 Pack Weld On Dump Trailer Hinges

Coloch’s 4-pack weld-on hinges are designed for dump trailers and heavy-duty doors, featuring a 5-3/8″ length and a 2-1/4″ plate width. They offer ease-of-installation by direct welding, reducing the need for extra brackets. The hinges are built from steel with protective coatings to resist rust and corrosion, supporting long-term outdoor use. Best for: straightforward, direct-weld installations on dump trailers and truck gates where a sturdy, all-steel hinge is required.
Choose this if you want a simple, four-hinge kit that can handle multiple repair sites at once. Limitation: ensure your weld setup matches the hinge thickness and plate dimensions to avoid misalignment during installation.
Buying Guide
What trailer type are you upgrading?
RVs, utility trailers, dump trailers, or ramp gates each have distinct hinge needs. RV doors often require offset clearance to avoid interference with door frames, while ramp hinges emphasize long leafs and greaseable pivots for repeated movement.
Do you need greaseable hinges?
Greasable designs reduce friction and extend life in high-use doors. If the door opens many times daily or in dusty environments, grease fittings are beneficial.
Welding vs. bolt-on installation
Weld-on hinges offer a robust, permanent solution suitable for heavier doors or high-use applications. Bolt-on hinges provide easier installation and removal but may not handle the same load as weld-on options.
Corrosion resistance considerations
Outdoor exposure demands corrosion resistance. Zinc coatings or painted finishes help protect hinges over years of use in rain, humidity, and salt-exposed environments.
Span and leaf size
Measure door width, hinge leaf, and mounting hole spacing to ensure compatibility. Mismatched spans can cause improper swing or binding.

FAQ
- Q: Are weld-on hinges suitable for all trailers? A: They’re ideal for heavy doors and permanent installations; verify material thickness and frame compatibility before welding.
- Q: Can I mix hinge brands on the same trailer? A: Mixing is possible if mounting patterns and load ratings match, but uniform hinge design often ensures balanced operation.
- Q: How do I maintain hinge life? A: Regular lubrication at grease fittings and periodic inspection for corrosion help maintain smooth operation.
- Q: What clearance should I expect with offset hinges? A: Offset designs create extra room at the hinge line; ensure your door frame and latch alignment remain unobstructed.
