Hello, To give you a bit of an overview of this hardware, the part in the photo is indeed the Johnson 23-307 top pivot bracket. This bracket is supposed to be stationary and it will receive the 23-121 spring-loaded top pivot to act as a hinge in conjunction with the 23-312 bottom pivot bracket and the 23-151 adjusting pivot. The screw in the 23-307 socket locks it in place. The bracket is not meant to slide but the spring-loaded pin at the top of the other half of the door is meant to slide in the track. I hope this helps you understand these doors and how they function a bit better. Thanks for posting! |
