I'm fairly sure these don't exist, but I have a question about re-screening a Florida pool cage/lanai (or for that matter a pool cage/lanai in any other State....lol). I have some screens I need to replace (I have miserably been there, done that a few other times), now since I have so many lower screens that need to be replaced I'm wondering if there are tools or other things that can hold the screen in place square & taught once cut so my hands are free to roll in the spline. My wingspan can't get the screen square, in place, & run the spline at the same time. Does anyone know of any such tool or tools other than calling "the guy" to be able to do this myself.....DIY? Thank you in advance for steering me in the right direction!!!
