Fearures: * Great for belts, light duty straps and light to medium duty tie downs. They close with a positive lock and do not slip. * Cam lock buckles are good for straps that require more frequent adjustment, rather than quick release or closure, which is the main advantage to the side release buckle. It have a lever with an off center cam that forces it to compress the webbing into the back of the buckle when the lever is pushed down.
