Picture rail hooks for French Gallery Rods Picture Hanging System. Supports up to 33 lbs.

Pack includes 4 Silver Monkey Hangers.
Adjustable clamping picture hooks slide onto square gallery j rods and will ‘lock' in place with the weight of the art.
Needs at least 3lbs of weight on the picture hook to lock in place. For lighter frames and artwork, you can add fishing line weights to the back of the object to stop the hook from sliding.
