Overview
The REP WP-4100-05-fba is a pair of plates combining iron, rubber, and stainless steel, weighing about 4.6 kilograms, roughly 10 pounds, for the pair, which points to 5 pound plates sold two to a set.
The rubber coating over an iron core is a common way to protect floors and the plate itself from chipping, while stainless steel hardware typically shows up around the center hub. The listed color field reads B: 5lb Pair, which lines up with the total weight and piece count, but the bore diameter is not given, so confirm it fits your bar before ordering.
- Iron, rubber, and stainless steel build
- 5 lb pair (about 4.6 kg total)
- Rubber-coated for floor protection
- REP brand
Who it's for
Suits a lifter who wants small, protected increments for fine-tuning a working weight, especially in a home setup where floor protection matters. Not intended as heavy primary plates given the 5 lb size.
Strengths and trade-offs
Drawn from this product's published specifications.
- Rubber coating protects floors and bar sleeves
- Stainless steel hardware for durability
- Sold as a matched pair
- Bore diameter not specified
- Only a 5 lb pair, not a full set
Performance notes
Rubber coating absorbs impact when a plate is set down or dropped, reducing noise and floor damage compared to bare iron, while the iron core keeps the plate dense enough to stay compact for its weight.
