4x4 Post Cap String Light Hooks
A weather cap for a nominal 4x4 fence or deck post (88.9 mm actual) with a 91 mm square socket, 20 mm engagement and two M4 clearance holes so it screws down and won't blow off. Twin horns on opposite faces carry a cafe-string-light cable in an 8 mm wide, 10 mm deep slot; overall 127 x 97 x 50 mm with a hollow 50-degree pyramid roof that sheds water and prints support-free.
