Overview
The CAP OSBIS-75#2 is a set of cast iron weight plates sold as 14 pieces with a combined item weight of 75 pounds, finished in black. Splitting 75 pounds across 14 plates points to a set of smaller increment plates rather than a couple of large ones.
The listing does not state whether these plates use a standard 1 inch or Olympic 2 inch bore, so buyers should check bar compatibility separately before ordering. What is clear is that with 14 pieces making up 75 pounds total, this reads as a fractional or small-increment set useful for fine-tuning load rather than heavy single-plate jumps.
- 14 piece plate set
- 75 pound combined item weight
- Cast iron material
- Black finish
Who it's for
Suits lifters who want small weight increments for progressive loading, such as accessory lifts or dumbbell handle loading. Not the right pick if you are looking for a couple of large plates to jump weight quickly, or if you need Olympic bore confirmed before buying.
Strengths and trade-offs
Drawn from this product's published specifications.
- 14 pieces allow fine weight increments
- Cast iron construction
- Bore size (standard vs Olympic) not specified
- Bare cast iron can mark floors and equipment
Performance notes
Cast iron plates in a multi-piece set like this are typically used to add small jumps to a lift, letting you increase load in smaller steps than a single large plate allows. Being unbanded cast iron, they will be noisier and can chip paint on contact compared to rubber-coated plates.
