Matrix Dumbbells, Kettlebells and Plates
Round, Hex and Multi-Sided Dumbbells, Kettlebells, Plates and Bars
Rubber or urethane, round or hex: the shape also decides the rack, since round dumbbells sit in saddles or cradles and hex and multi-sided ones on flat trays. Each product page lists the published weight range and handle size, and the storage page shows the racks.

Matrix Free Weights — questions
Is this the complete Matrix Free Weights range?
No — Matrix publishes more: neoprene dumbbells, fixed barbells, power, precision and training bars, trap and safety squat bars, Group X barbells and plates, and eight more cable attachments. This page shows twelve, one to five of each type; ask for the complete line sheet when you request a quote.
Can Matrix Free Weights be mixed with other brands, or other Matrix categories?
Yes to both. Matrix Free Weights pairs easily with Matrix's own other categories, or with any of the other manufacturers Fit Supply carries — the mix is built around what the room needs.
What is the difference between Matrix rubber and urethane dumbbells?
The coating. Matrix's round rubber dumbbell has a solid steel core inside a virgin-rubber exterior; its urethane dumbbells use premium high-grade urethane and come round, hex or multi-sided, the multi-sided line running heaviest, to 150 lb. Both use a 1.25-inch handle through 50 lb and a 1.37-inch handle above it.
