Manufactured from steel with either a steel loose or fixed pin. Being steel these butt hinges will rust if exposed to damp environment and are therefore not recommended for use in high corrosion coastal areas. The smaller sizes are used for hanging cabinet doors and display or utility boxes.
Available in sizes 40mm, 50mm 63mm, 75mm and 100mm long. They are avalable either unplated self colour steel finish or a decorative brass plated finish
Also available is a range loose pin hinges available which are used extensively to hang internal doors. 90mm and 100mm sizes are available and finished as either brass plated, zinc plated, polished chrome and 100mm in satin chrome The hinge construction is made of 2 leaves with the "knuckle" running down the middle connecting the 2 leaves and the pin is removable. A tip is to keep this pin oiled or smeared with some vaseline for really free movement.
The length is measured down the knuckle or the side of the hinge The width is the overall measurement of the hinge lying flat with the leaves open.
