An adjustable hinge includes a tension spring having a first end and an opposite second end, the second end of the tension spring being fixed relative to a swing arm hinge mount, a pin having a head including a plurality of projections about a circumference of the head and an opposite end of the pin spaced from the head. The projections of the head are configured to be received by the recesses of a base plate hinge mount, and the pin is positioned to extend through the base plate hinge mount and the swing arm hinge mount and to cooperate with the tension spring so that a first end of the spring is fixed relative to the head of the pin, and then the head of the pin is rotated the first end of the spring also rotates.
