Zwinger-Stapelset

The acorn nuts gave the whole stack a clean, finished look that feels way more secure than the zip ties I was using before. Took maybe ten minutes to lock two kennels together, and the stainless hardware hasn’t shown a speck of rust after a month in the garage. Solid buy.

The hex head screws threaded in smoothly with a standard wrench, and the acorn nuts gave it a clean, finished look once everything was snug. I’ve got three kennels stacked now and the whole thing feels rock solid, no wobble even when my dog bumps against it.

I was dreading the setup, but the stainless steel acorn nuts and hex head screws made it feel rock solid once everything was snug. The brackets line up cleanly between the kennels, so even with two heavy crates on top of each other, there's zero wobble when my dogs bump around inside.
