Overview
A CAP weight plate, model RSG-100T3, made from cast iron and weighing 100 pounds, meant as a single heavy disc for loading a standard barbell for serious lifters.
At 100 pounds this is a heavy single plate meant for loading a barbell rather than a light accessory plate, and cast iron keeps it durable under repeated heavy loading.

Who it's for
Suits experienced lifters loading heavy barbell work who need a single 100 pound plate. Not for beginners or anyone needing lighter increments to progress.
Strengths and trade-offs
Drawn from this product's published specifications.
- 100 lb single plate for heavy loading
- Cast iron durability
- No rubber coating to protect floors or reduce noise
- Too heavy to use for incremental progression alone
Performance notes
Cast iron gives the plate the density needed to pack 100 pounds into a compact disc, though it also means it lacks the rubber coating that protects floors and cuts down noise.
