SERTT Weight Cable Pulley System Gym

Name: SERTT Weight Cable Pulley System Gym
Brand: Amazon
Rating: 3.67 (3 reviews)

The SERTT Weight Cable Pulley System is a DIY cable-attachment kit that turns a power rack, squat rack, or pull-up bar into a makeshift cable station without buying a dedicated machine. The kit centers on two spinning pulleys, a set of chain links and carabiners for adjusting cable length and mounting height, and a loading pin that accepts both 1” standard and 2” Olympic plates, rated to handle up to 330 lbs.

Reviewers who set it up on a rack or pull-up bar consistently praise its versatility – one worked through five distinct rigging configurations (biceps curls, tricep pushdowns, lat-style pulldowns, rows, and flies) using only the included hardware – and call out solid welds and smooth pulley rotation as standout build details. The catch is real, not cosmetic: the cable can jump off the top pulley’s groove if it isn’t pulled straight down through a rep, and the whole system only works as well as the anchor point it’s rigged to – a genuinely sturdy rack or bar is required, since an improvised household bar isn’t rated for the load. No long pulldown bar ships in the box, so a lat-pulldown-style setup means supplying one separately or rigging the included chain to a bar you already own.

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 budget DIY cable pulley kit that earns its keep on versatility: reviewers rigged it for lat pulldowns, rows, tricep pushdowns, bicep curls, and flies off a single power rack or pull-up bar using the included pulleys, chains, and carabiners. Versatility is the standout — one reviewer worked through five distinct configurations with the same kit. Functionality is the weak spot: the cable can jump off the top pulley wheel if you don’t pull it straight down, and the whole system depends on a genuinely sturdy anchor point rather than a flimsy household bar.

+Versatility: reconfigures with the included pulleys, chains, and carabiners into at least five different rigs for biceps, triceps, lat pulldowns, rows, and flies (YouTube: TallRussian707)
+Build quality: solid welds and heavy-duty materials, with a loading pin that fits both 1" standard and 2" Olympic plates (YouTube: Training at 45; HomeGear360)
+Functionality: smooth-turning pulleys let the cable be angled freely mid-set (YouTube: TallRussian707)
+Value: backed by a 120-day money-back guarantee and 24-month replacement warranty, with support reported to respond within about 12 hours (Well and Fit Daily; HomeGear360)

−Functionality: needs a genuinely sturdy anchor bar or rack — an improvised household bar isn't rated for it (YouTube: TallRussian707)
−Versatility: no long bar attachment is included in the kit itself, so lat-pulldown-style bars have to be supplied separately or rigged with the included chain (YouTube: Training at 45)
−Value: GymRadar's own rating sits at a middling 3.67/5, and the sample is thin (n=3), so it's not yet corroborated at scale (GymRadar)
−Durability: only first-impression/unboxing coverage exists so far — no long-term wear reports (this knowledge base)
