Overview
The Signature AT2IN-2.5P is a 2.5 lb cast iron plate with an Olympic 2-inch center hole, priced at $9.99. These are the kind of small plates you add to both sides of a barbell when you want to bump weight up by 5 lbs total per session.
The 4.6-star rating from 407 reviews is strong for a micro-plate at this price. Piece count is not listed in the product data, so confirm on the product page whether this is a single plate or a pair.
Bare cast iron at this size will be thin on the sleeve. Ensure they load flush and that collars can still grip the bar properly. Gymso is an Amazon Associate and earns from qualifying purchases.
