1 / 4CAP Barbell RB-57TB 57-Inch Standard Threaded Bar
The CAP Barbell RB-57TB is a 57-inch solid steel bar for standard 1-inch weight plates. Its threaded ends and included star-lock collars suit home strength training, while the listing gives conflicting load limits that buyers should resolve before loading it heavily.

Pros and cons
Pros
- Includes star-lock collars, so the stated bar-and-collar setup is ready for compatible plates.
- The 57-inch length offers a shorter option for home setups than longer bars.
- Knurled grip is specified for hand contact during lifts.
Cons
- The listing's stated capacity is low relative to many heavy-load training needs, and its two capacity claims do not agree.

What to know before buying
Listing details to confirm
Capacity claims conflict: one product detail says 68.03 kg, while feature and description text recommend 150 lbs. These are not the same stated limit, so confirm the applicable load rating before use. Customer feedback also reports disagreement about fit and a concern about black paint peeling on the threads.

Customer feedback highlights perceived quality, size and value, while also raising a concern about paint peeling on the threaded ends and reporting mixed experiences with fit. These perceptions may matter for frequent use or if close plate-and-collar fit is important. The listing specifies a 57-inch bar for 1-inch plates, but its capacity claims conflict, so feedback does not establish a safe load limit.
Positive themes
- Customers describe the bar as good quality and appreciate its size and value.
Negative themes
- A customer-feedback summary reports that black paint may peel easily on the threads.
Mixed feedback
- Customer feedback describes disagreement about fit.
Frequently asked questions
Which weight plates fit this bar?
The listing says the bar accommodates standard weight plates with 1-inch center holes.
Are collars included?
The product title and description claim star-lock collars are included, and the contents list names the barbell. Check the selected listing if collar inclusion is essential.
What is the maximum recommended load?
The listing is inconsistent. One detail gives 68.03 kg, while feature and description text state 150 lbs. Confirm the applicable limit before loading the bar.
What should I know about the finish?
The listing describes a black powder coat. Customer feedback includes a report of paint peeling on the threads, so finish durability may matter if the threaded ends are handled frequently.
