What to know before buying

Listing details to confirm

Listing dimensions are inconsistent: one entry gives 83.8D x 58.4W x 83.8H centimetres, while another gives 62.51 x 57.99 x 83.49 cm; 11.4 kg. Capacity claims also conflict, with 136.08 kg listed in product details and over 500 lbs described as a tested capacity for the RK-CS19A / RK-CS19B series. Customer feedback reports that some Olympic bumper plates, including CAP bumper plates, may not sit flush, so confirm fit for your plates. Follow the assembly guidance to position the rack on a level indoor surface before fully tightening bolts.

Frequently asked questions

What plates is this rack listed for?

The listing describes it for Olympic plates with 2-inch centre holes. Customer feedback notes fit issues with some bumper plates, so compatibility with a particular set is not assured.

Does it hold an Olympic barbell?

The listing describes an integrated vertical Olympic bar holder.

What capacity and dimensions should I use for planning?

The product details list 136.08 kg capacity and dimensions of 83.8D x 58.4W x 83.8H centimetres, but other listing copy gives a different dimension set and a higher series-level capacity claim. Treat these details as unresolved.
