self closing spring for fence gate or garden shed door

Steel spring for automatically closing doors and gates. This measures about 13" long over the mounting brackets. It is designed to be mounted on the hinged side of the gate or door with one end on either side of the joint. When the door or gate is opened, the spring is twisted and so when it is released, the door or gate automatically closes.

This has black paint and has never been used, the hardware is still sealed in a small plastic bag.
