Heavy-Duty MAXX Ball Bearing Knock-In Hinge Set | Fits 65x65 & 75x75 SHS
Engineered for maximum reliability, strength, and ease of installation, the MAXX Ball Bearing Hinge Set is the next-generation upgrade to our classic knock-in gate hinge. Designed specifically to fit inside 65x65mm and 75x75mm SHS (Square Hollow Section) steel tubing, this top-and-bottom hinge pair offers superior weight distribution, effortless adjustability, and long-term weather protection for heavy-duty swing gates.
Key Features & Product Upgrades
- Heavy-Duty 450kg Load Capacity: Heavy-duty construction handles heavy residential, commercial, or security gates up to 450kg across standard 65x65 and 75x75 SHS posts.
- Precision Fine Adjustment System:
- 33mm Adjustable Slot Position: Allows generous lateral movement during installation or post-settlement adjustments.
- Interlocking Sawtooth Plate (1mm Depth): Machined positive-locking serrations prevent slippage over time, ensuring your gate alignment stays fixed under heavy loads.
- Enhanced Weather Protection & Maintenance:
- Integrated 2.3mm Water Stop Lip: The top hinge block features a precision-machined 2.3mm raised lip to divert water away, protecting internal bearings from moisture and corrosion.
- Accessible Grease Nipple: Built-in grease zerk allows easy, direct lubrication without dismantling the hinge assembly.
- Slimline & Premium Hardware Build:
- Slim 10.6mm Profile: Minimizes gate-to-post gaps for a clean, modern architectural finish.
- Stainless Steel Fasteners: Upgraded stainless steel hardware resists corrosion and binding in harsh outdoor environments.
