***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. 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. As a direct replacement you will not spend hours modifying your door or drilling new holes in the steel. Installation does not involve a long down-time involved or dealing with a rigged up door that binds because the hinges are mismatched. The problem with the original hinge on these doors isn't due to the plastic. There are many hinges that are plastic that work fine. The problem is the plastic half of these particular hinges wasn't designed to last, it was designed for ease of assembly by the 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. You will receive one hinge half shown as well as instructions sent via messages. The design of the original hinges required a high pressure forced fit just to connect the plastic half to the metal half of the hinge. Installing this new piece does not require any such force. As for preparation while your order is en route there is no need to remove the metal half of your hinge. Leave it in place on your door. Replacing this hinge piece is 60x cheaper than replacing your whole garage door($2000k average nationwide) or making lots of new holes in the thin steel door trying to modify your door to make it work differently. Long projects like that never come out quite right. This heavy duty replacement piece is "one and done." 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 online because of all the middle men. Otherwise a direct sale would only cost about $20. If it helps 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. Free shipping in the U.S. If there's a problem let me know and I'll work with you.
