These 5-knuckle hinges are seriously heavy-duty! This 6-pack gives you everything you need for multiple doors, with each hinge made from thick 0.090-inch steel that can handle constant use without wearing out. The 270-degree rotation is awesome - way more than standard hinges, giving doors a wider swing that's perfect for high-traffic areas. Designed for 3/4-inch thick doors and side panels, they fit perfectly without any modifications. The non-removable knurled pins add security, and the tumbled edges mean no sharp bits to worry about during installation. You get 54 matching screws included too, so you've got everything needed to get these installed quickly. The stainless steel construction resists corrosion and looks professional in any setting. Perfect for hospitals, schools, offices, or any commercial space where doors get heavy use. They're also great for residential heavy doors that need extra support. The installation is straightforward - the broached knuckles make pin alignment easy, and the countersunk holes fit the high-strength screws perfectly. If you're tired of flimsy hinges that sag or fail after a few years, these commercial-grade hinges are the solution. They're built to last through years of constant opening and closing without any issues. Seriously, for the price, you're getting professional quality that will outlast the doors they're installed on.
