PR-4000 offers finer adjustment around the bench. PR-5000 opens the matching one-inch attachment range.
PR-4000 would be my choice for a barbell gym: I’d take the finer bench adjustment when its attachment range covered my plans. I’d move to PR-5000 for a specific one-inch accessory or the locally listed PR-5000 Ares build. Their published rackable capacity is the same.
PR-4000 gives finer J-cup and safety positioning through the bench zone.

PR-5000 is the appropriate frame when your chosen accessories require its one-inch holes.

Its one-inch hole spacing through the bench zone allows positions between the PR-5000’s two-inch steps. For someone whose preferred pressing setup falls between holes, that is more valuable than a larger attachment bolt. PR-5000 numbers every hole; PR-4000 numbers every fifth. Full numbering helps record setups, while the closer spacing changes the positions available.
Both frames use nominal three-inch-square, 11-gauge uprights. Hole size, spacing and the exact attachment determine fit. A three-inch frame from another brand is not enough information to establish compatibility.
| Decision | PR-4000 | PR-5000 |
|---|---|---|
| Attachment holes | 5/8 in | 1 in |
| Bench-zone spacing | 1 in | 2 in |
| Other hole spacing | 2 in | 2 in |
| Published rackable capacity | 1,000 lb | 1,000 lb |
| Reason to choose this frame | Finer bench adjustment and a suitable 5/8-in accessory list | Specific one-inch accessories and a matched cable build |
Gym and Fitness lists both systems in Australia. The PR-4000 base listing begins with 80-inch uprights and 24-inch crossmembers, while taller or deeper configurations change the order. Include the required rear crossmember, J-cups, safeties and the specified anchoring or stabilisers in both quotes.
For value, stop at the frame and attachments that cover your actual lifts. Put any saving into the bar, plates and bench. For a larger cable build, choose the rack around the exact locally supplied kit: the Australian six-post Ares listing is PR-5000. That is a sound reason to choose the system before buying accessories for another one.
Specifications are for the packages described in the linked profiles. How I compare equipment.
Ares upgrades a compatible REP rack. FM-6 Twin is a complete rack purchase. That distinction can decide the whole budget.
