The UPS Low is Surplus Strength’s low-pulley add-on for its UPS High cable attachment, mounting flush to a rack’s lower crossmember with a built-in footplate sized for low rows, bicep curls, hamstring curls, and loaded hip hinges. It shares the UPS High’s dual-pulley design – which reviewers credit with mitigating the sway common to single-pulley cable attachments – and adds only 12-14 inches of extension with essentially no floor footprint beyond the loading pin and plates.

Owners consistently praise the build: 11-gauge steel, stainless hardware, UHMW inserts protecting both cable and rack finish, and welds one 3-year owner called some of the best of any equipment in his gym. The main tradeoffs are cost – $275 standalone, and roughly $670-$900 once paired with the UPS High and accessories – and setup time, which led at least one long-term owner to use the low-row attachment less often than the high unit alone.

What is a Rack Attachment?

What rack attachments are

Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.

Compatibility comes first

An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.

A well-regarded low-pulley add-on for Surplus Strength’s UPS High, and one of the few rack-mounted cable attachments reviewers describe as feeling genuinely premium. Its standout dimension is build quality: 11-gauge steel, laser-cut logo plates, UHMW inserts to protect both cable and rack, and welds one longtime owner called “some of the best… on any of the equipment” they own. Functionality is close behind — a dual-pulley design that mitigates the sway common to single-pulley systems, a built-in footplate for low rows, and near-zero added footprint since it mounts flush to a lower crossmember. Value is the weakest dimension: at $275 standalone (and roughly $670–$900 once paired with the UPS High), it costs noticeably more than DIY or big-box cable attachments, and one reviewer flagged the setup time as enough of a hassle that they used the low attachment less often than the high unit.

  • Value: GymRadar's own on-site rating sample is thin (3.89/5, n=3), so it isn't strong independent confirmation on its own (GymRadar aggregate)
