The EZ Leaf Bag is a direct replacement for the Leaf Master, Leaf Bagger & the Leaf Catcher. It is designed to capture the smallest of particles and is 5 times more durable than the competition. The EZ Leaf Bag contains an o-ring that is designed to snap right onto the majority of leaf catchers on the market. The sewn-in foam allows maximum leaf capacity which means less time cleaning the bag and more time cleaning your pool!
