Below is a list of Latches manufacturers from Torrington, Connecticut. Latches are a type of mechanical device used to fasten doors, windows, cabinets and other such items that can be either open or closed. Traditionally, latches have been used only to hold doors in the closed position, not to lock them. Bolts, on the other hand, have been used to only lock, though Bolt latches may serve only as fasteners. More recently, however, latches have emerged that are able to both lock and fasten a door or other object.
