Something like, say,
this?
I have a locally built cage essentially based off a Rogue R3. That cage I posted is what I would someday like to replace mine with, but I would also need to extend my platform, as I would be loosing a good foot for the included plate storage. Stupid crooked floor.
My cage has gotten almost two years of daily use and still looks brand new. I wobbles a bit when I do chins even bolted to the wood, but never to the point of feeling unstable. I have no regrets/second thoughts about getting or using the one I have.
