Our standard kit is engineered to withstand up to 2,900 PSI — perfect for most dogs. But for the most determined chewers, we added a third layer: 19-gauge, steel, vinyl-coated welded wire mesh with a 1/2" opening. Combined with our two standard layers, the fence can withstand up to 4,000 PSI.
The holes don't align between layers, making it nearly impossible for a dog to get their teeth in. For reference: standard chain link handles ~1,000 PSI; wood fences 550–700 PSI; vinyl even less. We've had falling trees that couldn't break our fence. Its slight flex — similar to a suspension bridge — lets all 12–13 components work together effectively.
We offer support seven days a week, along with detailed installation videos and written instructions — use both for the best results, especially for MAX installations at 6 or 7 feet.
