A spring hinge is a simple device that keeps a door in place. It is a two leaf mechanism with a leaf at each end that is secured to the door frame. It requires only a brief contact between the two leaves to keep the door closed. This type of hinge is generally used on doors that are relatively light.

Single washer washers are not only for domestic use anymore. They are being used by many corporations and other organizations to protect valuable property from thieves or trespassers.
