Fat Bar - Olympic Curl Bar Cable Attachment

Name: Fat Bar - Olympic Curl Bar Cable Attachment
Brand: Bells of Steel
Rating: 4.44 (3 reviews)

Bells of Steel’s Fat Bar Olympic Curl Bar Cable Attachment is a 2-in-1 tool: a fat-grip cable attachment for tricep pushdowns and cable curls, and a standalone, plate-loaded EZ curl bar for barbell work. The thicker (~50mm) grip diameter is deliberately harder to hold than a standard bar, forcing the hands and forearms to work harder and building grip strength as a side effect of normal arm training. An independently rotating eyelet connects it to a cable machine (carabiner required, sold separately), letting the bar spin freely through a rep so the wrists and elbows aren’t fighting cable inertia. Taken off the cable, its Olympic-sized sleeves accept standard weight plates, so it also functions as a dedicated curl bar for EZ curls, skull crushers, and similar exercises – independent reviewer Matt Rosenman called this dual-purpose design a “no-brainer” buy for anyone in the market for a curl bar, since it undercuts the price of Bells of Steel’s own standalone curl bar while adding cable-attachment versatility on top.

What is a Cable Attachment?

What cable attachments are

Cable attachments are the handles and bars that clip to a cable machine, functional trainer, or lat/row station to change the exercise — lat bars, triceps ropes, single-D handles, row/close-grip handles, ankle straps, and more. A small set of them turns one cable stack into dozens of movements.

What to look for

A rotating swivel or ball-bearing joint keeps the cable from twisting and lets the handle track your arm; comfortable, durable grips (knurled metal, rubber, or coated nylon) survive heavy use; and a standard carabiner or snap fits most machines. Match the attachment to the exercises you actually train rather than buying a giant kit you won’t use.

Bells of Steel’s Fat Bar Olympic Curl Bar Cable Attachment is a 2-in-1 tool – a rotating fat-grip cable attachment that also stands alone as a plate-loaded EZ curl bar. Versatility is the standout: independent reviewer Matt Rosenman singled it out as the best piece in Bells of Steel’s fat-bar lineup, calling it “a no-brainer” for anyone shopping for a curl bar, since it replaces both a dedicated cable attachment and a standalone curl bar for less than the cost of Bells of Steel’s regular (non-cable) curl bar alone. Functionality holds up too – the independently rotating eyelet is designed to remove wrist strain from cable curls and pushdowns, and Rosenman praised the knurling as “really impressive.” Build quality and durability are harder to confirm independently: coverage is limited to one YouTube review and the manufacturer’s own materials, so there’s no long-term durability data or a dedicated editorial teardown. Value reads well at its accessory price point given the dual-purpose design, though buyers should budget for a separate carabiner to use it on a cable machine.

+Versatility: doubles as a cable attachment and a standalone plate-loaded EZ curl bar, replacing two purchases with one (Matt Rosenman / YouTube)
+Functionality: independently rotating eyelet connection reduces wrist/elbow strain during cable curls and pushdowns (Bells of Steel product page)
+Value: priced below Bells of Steel's own standalone (non-cable) curl bar while adding cable-attachment functionality on top (Matt Rosenman / YouTube)
+Build quality: knurling described as "really impressive" and noticeably better than the other attachments in the same lineup (Matt Rosenman / YouTube)
+Functionality: fat-grip diameter (~50mm) adds grip/forearm training stimulus to standard curl and pushdown movements (Bells of Steel product page; 306 Fitness reseller listing)

−Durability: no long-term ownership data or independent teardown exists yet -- coverage is limited to one hands-on video review
−Value: requires a separate carabiner (not included) to use as a cable attachment, an extra small purchase
−Build quality: minor spec discrepancies between the manufacturer's US listing and an independent CAD reseller (17 lb/46 in/chrome vs 15 lb/47.25 in/powder coat) suggest inconsistent spec reporting across markets
−Versatility: standalone curl-bar use is fixed to one grip width/shape (EZ curl), unlike a straight bar or multi-grip attachment
