The WF Athletic Supply Rubber Hex Dumbbell Set is a fixed-weight dumbbell set that includes pairs of 5, 10, 15, 20, and 25 LB dumbbells with an A-frame storage rack. Each dumbbell is built with an ASTM A48 Class 20 grey iron head encased in heavy-duty rubber and an AISI 1018 cold-rolled solid steel handle with chrome plating and knurled grip. The A-frame rack stores all five pairs vertically in under 1.3 square feet of floor space.
Five pairs, one compact rack — the WF Athletic Supply set fits in the corner of a bedroom, garage, or office without taking over the room.
Why This Dumbbell Set
ASTM A48 Class 20 grey iron heads — high-tensile cast iron construction rated for impact resistance; rubber encased in low-odor, floor-protective heavy-duty rubber.
AISI 1018 cold-rolled steel handles — solid steel core prevents bending or breaking; chrome-plated with knurling for grip security across all grip styles.
Hex heads prevent rolling — hexagonal shape keeps dumbbells stationary on the floor or rack between sets.
Compact A-frame rack — stores all five pairs vertically; base footprint of approximately 13" L × 14" W × 26" H, requiring under 1.3 sq ft of floor space.
1-year limited warranty — covers structural rack failure, handle defects, and rubber head separation under normal residential use.
