7" (3/4) J-Bolt Adjustable Barrel Hinges
Engineered for heavy-duty gates and doors, our 7" J-Bolt Adjustable Barrel Hinges provide a robust, smooth-swinging pivot point. The weld-on design ensures maximum strength and security, while the adjustable J-bolt allows for precise alignment and easy installation. These industrial-grade hinges are ideal for fabrication and MRO projects requiring reliable, long-lasting performance.
- Heavy-Duty Steel Construction
- Weld-On Installation
- Adjustable J-Bolt for Alignment
- Industrial Gates & Heavy Doors
Constructed from high-tensile, low-carbon steel, these barrel hinges are built to withstand significant weight and continuous use. The design features a precision-machined pivot pin and bushing for smooth, low-friction operation, minimizing wear over time. The solid steel body is designed for a permanent weld-on connection to steel posts and gate frames, creating a unified structure with exceptional load-bearing capacity. The 3/4" J-bolt component is made from hardened steel, providing secure attachment and the flexibility to adjust gate alignment post-installation.
These J-bolt hinges are the professional's choice for fabricating and repairing heavy swinging gates, industrial access doors, trailer ramps, and custom enclosures. Their robust construction makes them suitable for high-traffic commercial and industrial environments, including warehouses, manufacturing facilities, and secure perimeters. The adjustability is particularly valuable for correcting gate sag or accommodating ground shifts, making them a versatile solution for both new installations and critical MRO (Maintenance, Repair, and Operations) tasks on existing structures in the Los Angeles area.

Target Users
These hinges are primarily used by metal fabricators, welding contractors, and maintenance technicians for commercial and industrial projects. They are essential components for anyone building or repairing heavy steel gates, security enclosures, and custom equipment that requires a strong, adjustable pivot.
Finish Options
Our 7" J-Bolt Adjustable Barrel Hinges are supplied in a raw, unfinished steel condition. This provides a clean surface that is ideal for welding directly to steel posts and frames. After installation, the hinges can be finished with industrial-grade primers and paints, such as DTM coatings, for superior corrosion resistance and a professional appearance.
How to Measure
To ensure the correct hinge selection, measure the weight and size of your gate or door. Verify that the 7" hinge length provides adequate support and that the 3/4" J-bolt fits your mounting configuration. The adjustable nature allows for flexibility, but initial placement is key. Measure the distance from the post to the gate frame to confirm proper swing clearance.
Example: For a 400 lb steel gate, specify two or three 7" J-Bolt Hinges depending on gate height and desired load distribution.
