Below is a list of Strap Hinges manufacturers from Covina, California. Strap hinges are a type of hinge with long straps that attach to the face of exterior and interior doors and cabinets while allowing for up to 180 degrees of swinging movement. As one of the earliest types of hinge, the strap hinge design is a relatively simple concept that can be customized and permuted in countless ways. Serving industries such as marine, automotive, construction, architectural, residential, commercial, wine, industrial and agricultural, strap hinges are intended to be used on flat surfaces and are ideal for barn and shed doors, gates, boxes and crates.
