In this storm, I used some strong 2 or 3 mm cord (climbing quality) and a trucker's hitch with a column that supports our roof at the other end from the latch. (I started with a standard taut line hitch, but it was not sufficiently taught. The trucker's hitch is easily tightened by the 2:1 mechanical advantage.) Even with that, the door itself was visibly flexing. You can remove the door, before the wind starts, but insects, frogs, etc. will probably use the entrance while it is open. The twine used at lumber yards to tie objects down to cars and trucks works well. Just use two or three Lengths of it for extra strength.
IAN (2022) occured before our closing and the rod on the closing piston was bent as a result of it slamming open. The technique above worked in Nicole, shortly after closing.
This time was different though. Two of the large lanai screens pulled out from the base. Peak winds were likely mid 60's mph here. Calling the pool installer later for screen replacement. They have all of the specs.
Another solution would be adding a horizontal beam at the level of the latch so there are two screens instead of one full height screen. That would prevent the flexing where it matters.

Yup, my HEAVY tool box and tie down strap was temporary. I’m thinking 1 or 2 simple sliding bolt latches would do the trick.
Like you said, it doesn’t take much for the stock latch to be forced open. It’s probably the weakest part of that door/latch assembly. |
