These stainless steel shower hinges are designed for frameless glass enclosures and support glass thicknesses from 8 mm to 12 mm. Each hinge holds up to 40 lbs. making them suitable for heavy-duty residential use in humid environments. The construction uses solid 4 mm thick stainless steel with stainless steel bearings instead of iron, enhancing corrosion resistance and structural integrity. A built-in elastic mechanism enables automatic closing when the door is within 25° of closure, ensuring quiet, smooth, and hands-free operation. The hinges open bidirectionally up to 90° with silent motion, thanks to precision engineering and integrated rubber buffers that protect glass surfaces from scratches or impact damage. Mounting hardware is included for straightforward installation, and the design accommodates standard configurations without requiring specialized tools. They function reliably not only on shower doors but also on patio doors, room dividers, and steam shower enclosures. The rubber padding minimizes vibration and prevents metal-to-glass contact during movement, contributing to long-term performance and reduced wear. Color: Black.
