LOT OF 4, 1 knob is stuck, but if you use a wrench or something can get it loose or reposition. These are made of aluminum and all are the same size. These would be used for someone customizing a boat, non magnetic aluminum with the cleat style knob, there is threading on underside of knob, so i assume they would be attached from the underside. These would take some cutom work to install, but are high quality and need a new home. Message with any questions you may have. Each plate measures 12″ x6-3/8″ With a half inch depth. Knob is about 1″ tall x just over 2″ long.
