Overview

A cast iron plate weighing 2.5 pounds with a 2-inch center hole sized for standard Olympic barbell sleeves, meant for fine-tuning a bar's total load in small increments.

This is a single microloading plate rather than a full set, so its job is topping up a bar between larger plates, not carrying the main load on its own. Cast iron has no rubber coating, so expect metal-on-metal noise when racking.

  • Cast iron construction
  • 2.5 lb weight
  • 2-inch Olympic center hole

Who it's for

Lifters who already own a plate set and need small increments to progress a lift. Not for anyone who wants a quiet, rubber-coated finish or a full set in one purchase.

Pros and cons

Pros
  • Fits standard 2-inch Olympic sleeves
  • Useful for small, precise load jumps
  • Durable cast iron build
Cons
  • No rubber coating, so it's noisy on the bar
  • Listed as a single plate, not a pair

Performance notes

Cast iron holds its shape under repeated loading and unloading, but bare metal can mark floors or gym mats and will clang against other iron plates on the bar.
