Is the Mikolo WR00 sturdy enough for heavy squats?

It is rated to 1000 lb and built from steel. That covers most home lifters, but the wall mount must be anchored into solid framing to reach that rating.

Does it really fold flat against the wall?

Yes. The rack folds back toward the wall to clear floor space between workouts. You unfold it for each session and lock it in place before loading the bar.

What comes in the box?

The rack frame, J hooks, a cable crossover machine and a lat pulldown. A barbell, weight plates and bench are not included.

Can I use it for cable crossovers and lat pulldowns?

Yes. The included cable crossover and lat pulldown run off the rack, so you can do cable flyes, rows and pulldowns alongside barbell lifts.

How much wall space and ceiling height does it need?

It mounts to a wall and folds back, so you need clear wall width for the folded frame and enough ceiling height to stand and press overhead. Check your room height before mounting.

Is it suitable for a commercial gym?

Mikolo rates it for commercial and gym use as well as home use. In a busy gym, the folding mechanism and cable attachments will see more wear than in a home setting.
