Hinges are mechanical devices that are designed to hold two objects together in a way that allows for a controlled rotation of one of them.
One of the most popular hinges are gate hinges also known as Tee Hinges. They hold a weight of the gate that is typically fixed to a fence pole or a wall. They can only hold a restricted weight so it is very important to check a weight of the gate before mounting.
This system can be integrated with almost any type of hinges including butt hinge, door hinge or window hinge.
