5-1/2" Nylon Cleat, For flagpoles 15'-25'
Your cleat should be placed at the most comfortable height for the person who will be raising & lowering the flag most often. Typically 4′-5′ above the ground.
To lessen snap banging sounds the cleat should be placed on the pole opposite of the sheave (pulley) in the truck. This allows the halyard to be more tightly secured to the pole.
