This is the same manufacturer-supported shared Utility Seat, supplied with 5/8-inch mounting pins and bundled with a pad. It is a commercial package of the same seat, not a second independent attachment model.
Use the specified supplied mounting pins: PR-4000 rack, Flip-Down Safeties and ISO Arms use 5/8-inch Band Pegs; Utility Seat installation on compatible Spotter Arms uses one-inch pins.
Check support position, rack alignment, cable clearance and the exact installed accessory.
For Utility Seat use on Spotter Arms, the rack must be floor-bolted or stabilized with Front Foot Extensions.
The Utility Seat leg-press arrangement requires installed compatible ISO Arms and cannot coexist with the Rear Base Stabilizer, Lat Pulldown & Low Row or Ares.
The documented Band Peg storage arrangement requires a six-post rack without Ares or Athena; remove the Utility Seat Pad before storage.
The Seat + Pad package inherits the same seat mounting, exercise, interference and storage restrictions.
