of the clip is not critical other than the bent u shaped portion is centered so that the convex side will protrude toward the screen panel and hold it in place the shape is not critical but is preferred that the shape be balanced so that the peak of the clip will be equal distance between the sidewalls of the screen frame panel when in place the clip will exert sufficient force to hold the screen panels in place but when necessary the screen panels are quickly and easily removed by forcing the panels out of their position thus the screen panels can be removed prior to a storm by removing some of the screen panels the wind and rain force will flow freely through the holes that remains after removing the screen panels and such removal shall prevent the wind and rain forces from exerting undue pressure on the screen enclosure thus the screen enclosures should remain intact in some instances it may be necessary to provide an additional support means for the screen panels when they are installed when the size of the screen panels is too large the pull force that the tensioned screen exerts on the screen frame structural members especially when the screen panel support members are made from aluminum will cause the support members.
