*** These hinges came in several different sizes. I need to know the length measurement of the plastic part of your hinge so I can send you the right version. *** I CANNOT SHIP WITHOUT THIS INFORMATION. These hinges came in 3 different lengths and 3 different hole spacings. Use the "Contact seller" button to tell me the length of your hinge or send me a photo of your hinge showing the measurement. This is a buying requirement to help prevent exchanges/shipping back and forth. This is for one replacement heavy duty polymer hinge half piece for the special half metal/half plastic garage door hinges found on many older garage doors. This is a direct replacement part in a heavy duty design using modern materials. The factory never offered spare hinges. As a direct replacement part you will not spend hours modifying your door or drilling new holes in the steel. Installation does not involve a long down-time or dealing with a rigged up door that binds because the hinges are mismatched. The problem with the original hinges on these doors isn't because they're plastic. The problem is the plastic piece wasn't made to last, it was designed for quick assembly by the original door installer. This heavy duty polymer version is 10x stronger and also allows the two halves to separate cleanly in most cases under extreme vertical stress without breaking. This allows you to fix the problem and then rejoin the two halves. The heavy duty version of the part you receive will look slightly different cosmetically from the images shown. Installation does not require specialized service. YOU JUST NEED A HANDYMAN or DIY. Don't pay a garage door company to install these. They charge too much. If you don't do DIY stuff you just need a handyman or a friend/neighbor who does. Replacing this hinge piece is 60x cheaper than replacing your whole garage door($2,000 average nationwide) or making lots of new holes in the thin steel door trying to modify your door to make it work differently. Projects like that never come out quite right and take hours/days of labor. Also a new $2k garage door will be 10x more noisy than your existing door. It's horrendous. This new heavy duty piece is a "one and done" direct replacement. As with all garage doors do not allow people or pets to stand under an open garage door and do not park under an open garage door. After manufacturing costs + seller fees + PayPal's transaction fees + postal shipping fees this is just barely worth selling on here because of all the middle men. If these help people avoid a major home expense and also maintain what is otherwise a perfectly good garage door then it's a win/win. Your garage door should be serviceable not disposable.
