When gazebo netting tears, the frame and roof are usually still sound, so replacing the walls costs far less than replacing the whole structure. This set fits a 9.8 by 12 foot four panel gazebo with a 6.8 foot drop to the ground, and it is worth measuring before ordering because other frame sizes will not hang correctly. Installation works like hanging a shower curtain: unfold the panels and slide each ring onto the round top piping. Zippered openings let people carry food and drinks in and out without unfastening a whole wall. The polyester mesh keeps flies and mosquitoes off a table while air still moves through, and out of season it also keeps leaves and debris from blowing into the space.
