For outdoor flags/banners with rope, you need snap hooks and grommets to set up.
Step 1: Decide where you want to put the snap hooks.
For a new flags, measure the distance between your flag’s grommets. This is the same as the distance between the snap hooks on the rope.
To replace old snap hooks, first ensure that any knots or other rope defects that would prevent the rope from threading through the pulley are at the bottom of the rope circle and the snap hooks are towards the top. Lower the flag and place the new snap hooks in the same spot as the previous snap hooks.
Step 2: Thread the snap hooks: First, slide a loop through the eye of the snap hooks. Then, place the loop over the top of the snap hooks and pull the rope tight.
