At Hardwaresource.com, our selection of Heavy Duty Hinges is second to none. We stock heavy duty sizes that not even the big name manufacturers have in stock. Try on for size an 8x8 ball bearing butt hinge that is close to ¼” thick and will support an 800-lb door. Wow, now that’s heavy door. Or, how about a Rixson center hung pivot hinge rated for 1000-lbs. I’ve always wondered how one would lift a 1000-lb door to place it in position? And heavy duty weld on hinges, yes, we have them up to 6x6. Have you ever considered, what has been designed to be a better type of piano hinge, a geared hinge or a Roton hinge? This style of continuous hinge is both heavy duty and tamper-proof, and they present a streamlined and contemporary look to any door. Strap Hinges, Tee Hinges, Spring Hinges, we have all in heavy duty grades that complete our vast selection of heavy weight hinges.
