Below is a list of Butt Hinges manufacturers from Nashau, New Hampshire. Butt hinges are a type of hinge with rectangular parts that fasten to two separate, parallel parts that close on each other, thus connecting them and allowing for swinging movement up to 180 degrees. One of the two most common types of recessed, or mortised, hinges, butt hinges do not necessary have to be mortised and can be surface-mounted as well.
