Bathroom stall hinges are confusing. Lots of manufacturers with lots of similar-but-not-identical designs.Hard to measure parts (especially when broken), lots of moving parts to consider...
But taking all of the parts together (bracket, insert, and pin for top hinges; or bracket, insert, pintle, and cam for bottom hinges), you can be fairly comfident in your choice.
We've done extensive cross-linking on these pages. So if you see the bracket you think is right, you can click on other parts used with it to make sure you have the right part.
Or send pictures to sales@langequip.com, and we'll do our best to help you. Please include photos of the door insert and any shots you can take of pins, pintles, and cams.
