Installation instructions both contradict each other and both are not correct. No instructions, no instructions — not how to size them nor how to install them. Waste of time, money, and packaging.

Easy to install with all necessary hardware to adjust the hinge and close tension.

These auto close hinges are very sturdy and well made. Works perfectly well and was a perfect fit for my existing old hinge. Comes with both wood and metal screws, along with everything needed to set the spring.

As for instructions. No squeaking sound. Easy to adjust and string enough to use 1 per door in a weather protected pen.

Same general pattern but off by. Over priced hard to use and adjust tension force.
