When rugged performance meets low-maintenance convenience, you get the Formed Steel Hinge Strap with Grease Fittings—the ideal hinge solution for heavy-duty trailer doors, utility compartments, equipment panels, and industrial access points. Built to handle the elements and designed for ease of service, this hinge is the perfect upgrade or replacement for hard-working vehicles and gear.
Whether you’re outfitting a custom trailer or retrofitting commercial fleet equipment, this heavy-duty strap hinge brings the strength, function, and reliability you need on the job, in the field, or on the road.
Heavy-Duty Formed Steel Construction
Built from formed steel and engineered to handle constant stress, this hinge is ready for demanding applications where load strength and structural integrity matter. The precision-formed steel body provides enhanced durability and weight distribution while maintaining a compact, professional appearance.
With an overall footprint of 3.85″ x 4.33″ and a height of 2.44″, this hinge delivers serious holding power in a relatively small package. It’s an ideal fit for medium to large swing doors and panel systems, especially in environments that involve frequent opening and closing.
Integrated Grease Fittings for Long-Term Use
Unlike standard hinges that wear out or seize over time, this model features built-in grease fittings (zerk fittings)—allowing for easy lubrication and ongoing smooth operation. Grease ports at the pivot points help extend service life by reducing friction, preventing moisture intrusion, and eliminating squeaks or stiffness.
This maintenance-friendly design is perfect for fleets, equipment trailers, and commercial rigs where uptime matters and preventative care can’t be skipped.
A few pumps of grease now and then will keep this hinge operating like new—even in dusty, wet, or corrosive conditions.
Compact Design, Big Utility
Despite its stout construction, this hinge maintains a compact footprint that suits a wide variety of uses. With a clean formed profile and tight tolerances, it offers a low-profile fit that minimizes visual bulk while delivering exceptional strength and functionality.
This makes it especially useful for:
-
Enclosed trailer rear and side doors
-
Ramp and gate systems
-
Utility box doors and compartments
-
Farm equipment and tool enclosures
-
Industrial cabinets and access panels
-
Work truck doors and mobile service units
It installs easily via weld-on or bolt-on applications, and pairs well with both OEM and custom-fabricated hardware systems.
Designed for the Real World
From rough roads to construction sites, this hinge is designed to keep up with your workday. The greaseable pivot resists dust, water, and impact stress, while the formed steel body ensures the hinge won’t twist or deform under heavy use. No matter what your day throws at it—heat, cold, grime, or weather—it stays secure, stable, and smooth.
Whether you’re in agriculture, construction, transportation, or trailer fabrication, this hinge is built for the wear and tear that comes with the territory.
