Frequently Asked Questions
Will these fractional plates fit my adjustable dumbbells?
They fit many standard adjustable dumbbell handles but not every model. Measure your handle/sleeve diameter and compare to the plate opening, and check whether your adjustable system uses collars or fixed locks—some users report a looser fit on uncommon sleeves.
How do I prevent these plates from sliding on the handle?
Use a collar or clamp if your dumbbell supports it, or pair the micro plates alongside a rubber or textured plate to reduce movement. Ensuring a snug fit and using collars during dynamic lifts will minimize slide.
Are these plates durable and odor-free?
These Micro Gainz plates are sintered steel with a powder-coat finish, which is durable and resists chipping better than painted alternatives. Unlike some rubber or PVC products, they’re unlikely to have persistent chemical odors; however, inspect for factory residue and wipe clean on arrival.
