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.

Pros and cons

Pros

100 lb single plate for heavy loading
Cast iron durability

Cons

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.
