What is everyone's practical experience with NexDome in high winds? The 7 small L-brackets seem like a minimalist approach to assuring stability in high (>50 mph [>80 kph]). Thanks for any responses.

The L brackets do seem lightweight, however I installed mine with 2 3/4" concrete lag screws into the concrete pad. We don't get 50mph winds so you might need bigger brackets. If you have room you might try using steel cable around the dome sunk into large concrete anchors in addition to the L brackets.
I can tell you from experience that the dome/shutter will fly off in high winds. The two rubber straps supplied with the dome, in MHO, aren't reliable. There are other posts where I've seen folks adding D-rings on the walls (attached to the center bolt on the aluminum uprights) and J hooks on the dome itself (like the ones supplied with the NexDome) to secure the dome to the walls.
Hope this helps.

Thank you, Steve. Very helpful. What do you mean by "using steel cable around the dome sunk into large concrete anchors?" Do you mean guy wires (cables) from the NexDome to a secure ground anchor?
When you use a D-Ring and J-Hook, I guess you must be using some kind of elastic cord between the two.
Again, thanks!!!
I guess they are called guy wires. I've seen them used on antenna's, trees that lean from the wind, tents, etc. Now that I think about it, they could only be used on the outside walls where the uprights are attached of the NexDome because those are stationary. I'm not sure how you'd attach them to the dome itself, at bolt points where the sections are attached, where they are temporarily used during high winds otherwise the dome wouldn't rotate.
Another option is to have a very sturdy cover over the NexDome with say D-rings along the base that can be staked or otherwise attached to anchors (in ground concrete blocks with eye bolts) with rope/ratchet straps.
I hope this helps. Good luck and please let use know what your solution is. And post photos too.
