Overview
A pair of 5 pound cast iron grip plates from JFIT, sold as two pieces for adding light, incremental load to barbells or plate-loaded machines.
Cast iron is the standard material for weight plates because it holds up to repeated drops and rack use better than coated alternatives. At 5 pounds each, this pair is meant for fine-tuning a load or working with lighter lifts rather than anchoring a heavy barbell session. The listing doesn't specify the center bore size, so confirm it matches your bar before ordering.
- Cast iron material
- 5 pounds per plate
- Sold as a pair
- Grip plate design
Who it's for
Useful for lifters who need small increments to fine-tune barbell load, or for lighter accessory lifts. Not a fit for anyone assembling a full plate set from scratch, since this is only a pair at 5 pounds each.
Strengths and trade-offs
Drawn from this product's published specifications.
- Durable cast iron construction
- Useful for fine load increments
- Sold as a matched pair
- Only 5 pounds per plate, not a full set
- Bore size not specified
Performance notes
Cast iron construction gives these plates the durability to handle rack contact and occasional drops without chipping. At 5 pounds per plate, the pair is built for incremental adjustment rather than serving as primary loading plates.
