CAP Barbell 300-Pound Rubber Grip Olympic Weight Plate Set Review (2026)

Who this set is for

This set suits someone building a home barbell setup from scratch and wanting squat, bench and deadlift weight without sourcing a bar and plates separately. Manufacturer and retailer listings for this 300 pound rubber grip set describe it as including a 7 foot Olympic bar and two spring clip collars alongside the plates, so it functions as a starter package rather than a plate only add-on. That makes it a good fit for a garage or basement gym where one order needs to cover the bar, collars and enough plates to progress through the main lifts for months. It suits lifters training with controlled reps rather than anyone doing Olympic style drops from overhead.

Specs and design explained

The plates break down as two 45 pound, two 35 pound, two 25 pound, two 10 pound, four 5 pound and two 2.5 pound plates, giving roughly 255 pounds of plates plus the bar itself. The included 7 foot bar measures 2 inch diameter sleeves, carries a rated 500 pound capacity, and has a black oxide finish with medium depth diamond knurling for grip. Plates are cast iron coated in rubber, which is where the set gets its name, and they use a large grip design with raised number markings so plates are easy to identify and carry with one hand while loading a bar.

Living with it

Assembly is mainly about attaching the spring clip collars once plates are loaded onto the sleeves, and the rubber coating on both the plates and cast iron core cuts down on the clanging noise that bare iron plates produce, along with reducing wear on a garage floor if a plate is set down harder than intended. The set ships in multiple boxes given the combined weight of bar and plates, so plan for a bit of unboxing and sorting on delivery. Because these are grip plates rather than bumper plates, they should be lowered under control rather than dropped, which also protects the rubber coating over time.

Trade-offs and how it compares

Against the CAP Barbell 300 Pound Olympic Weight Set with bar, this rubber grip version differs mainly in the rubber coating over cast iron rather than a painted or black oxide plate finish, which trades a bit of extra cost for quieter handling. Against Titan Fitness's individually sold bumper plates or the Yes4All 10 pound bumper pair, this set is better suited to controlled bench and squat work, while true bumper plates are the better call for anyone planning to drop loaded barbells from the top of a lift, such as Olympic style training. The rubber grip plates here are not designed to absorb that kind of impact repeatedly.

Verdict and who should pick something else

Choose this set if the plan is a complete home barbell station covering squats, bench and deadlifts, with a bar, collars and enough plate weight in one purchase, and if quieter handling than bare iron matters in a shared living space. It is a solid, practical starting point for structured strength training. Anyone planning Olympic lifts with regular drops from overhead, or who already owns a bar and only needs plates, should look at a dedicated bumper plate set instead, since these rubber grip plates are built for controlled lowering rather than repeated impact.
