Overview
A cast iron weight plate from Signature's SFAT line, weighing 2 pounds and finished in black. The listing data covers only this single plate rather than a set.
The SFAT-1IN45P model code points to a 1 inch center bore built for standard, non-Olympic bars and dumbbell handles, but only the 2 lb weight and black finish are directly confirmed in the listing. Anyone stacking a home rack should check hole size against their own bar before ordering.
- 2 lb cast iron plate
- Black finish
- Standard-bar model code (SFAT-1IN45P)
- Sold as an individual plate
Who it's for
Fits lifters who want a small increment to fine tune a barbell load on a standard 1 inch bar, or anyone building out a plate collection piece by piece. Not a fit for Olympic 2 inch sleeves.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cast iron build resists wear
- Useful for fine-tuning barbell load
- Compact, easy to store
- Only a single 2 lb plate confirmed here
- Bore size not stated outright in the listing
- No set or pair option shown in this data
Performance notes
Cast iron construction holds up to repeated loading and unloading without the plate wearing down, though at this weight it works as a fine adjustment rather than a workout centerpiece.
