Heavy-Duty Steel Box Hinge with Removable Pin and Oil Cup. Heavy-Duty Load Capacity: Engineered from solid steel to support massive industrial doors and equipment panels without deformation. Weld-On Installation: Provides a permanent, vibration-resistant bond that is significantly stronger than traditional bolted hinges. Integrated Grease Nipple: Features a top-mounted Zerk fitting for easy lubrication, ensuring smooth operation and extended service life. Removable Pin Design: Allows for quick lift-off of doors or gates for maintenance without the need to un-weld the hinge body. Precision Machined Fit: Tight tolerances between the pin and barrel minimize wobble and ensure precise alignment under heavy loads. Corrosion Resistant Finish: Treated surface protects against rust and wear in harsh environments like factories, warehouses, and outdoor sites.
