I am not sure who the manufacturer of this shower is. The door is getting hung up on the white part of the hinge. It is on a spring which seems to have expanded and now there is a lot of resistance to the white part being pressed down into the hinge apparatus as the door is pulled over it.

Hello,
Our best replacement option for your hinge would be the 10-081 but I recommend reviewing our product specifications to see if it could work for you. Thanks for posting!
