The detail
Six posts rather than four gives you a second bay behind the cage. The front four are where you lift; the rear two carry storage, attachments and a second plane of hole spacing. That is why the footprint is 77 inches deep against the 48 by 53 of the half rack — you are buying a rack and a storage bay welded into one structure.
Three heights — 95, 89 or 81 inches — is unusually flexible for a six-post rack. The 81-inch option fits a basement where a standard cage cannot stand, without giving up the six-post architecture.
One-inch hole spacing inside the bench area is what makes a rack good to bench in. On uniform 2-inch spacing the right J-cup height is usually between two holes.
A 1,000 lb capacity on 3x3 11-gauge is the serious-home standard, and it is the same as the half rack — the extra posts buy you depth and storage rather than capacity.
Note what is and is not in the box. Two heavy-duty J-cups, two L-foot brackets for floor anchoring, a foot spreader and all assembly hardware are included; floor anchors themselves are not. Budget for them — a six-post rack is stable enough that anchoring is optional for most people, but the brackets are there for a reason.
A 42-inch multi-grip pull-up bar comes standard.
Compare the Rogue RML-690, which is the same six-post idea on Monster Lite at 80 by 53 inches and 530 lb.
