PlateMate magnetic 1.25 lb donut microloading plates — pair for pro-style iron dumbbells, 2.5 lb incremental jumps

PlateMate 1.25 lb magnetic donut add-on weights (sold as a pair) clip onto compatible iron dumbbells to provide precise 2.5 lb incremental loading without a full extra dumbbell set.

These compact, donut-shaped magnetic microloading plates are designed to let lifters increase resistance in small, controlled steps. Each unit is 1.25 pounds; two attached—one on each dumbbell end—create a 2.5 lb increase per pair. PlateMate’s patented magnetic design is engineered for iron and cast-metal fitness equipment, giving you a low-cost, space-saving alternative to owning every intermediate dumbbell.

How do PlateMate donuts make microloading easier?

They attach quickly to the flat metal surface at the end of pro-style dumbbells so you can add or remove fractional weight between sets. Because each donut is only 1.25 lb, you can progress with smaller jumps, which helps when you’re stalling on strength gains or rehabilitating an injury.

• 1.25 lb per donut; 2.5 lb added when used as a pair
• Magnetic attachment for fast on/off adjustments
• Designed for precise incremental progress without new dumbbell purchases

Which gym equipment works with PlateMate 1.25 lb donuts?

They were made for iron and cast-iron dumbbells, compatible cast plates, and the flat metal faces on many stack-style machines. They are not universal; they won’t clip securely to rubber, urethane, neoprene, or vinyl-coated surfaces, and they will not fit an Olympic barbell shaft.

• Fits pro-style dumbbells with a metal end and a bolt-style center
• Works on cast iron plates and compatible weight stacks
• Does not adhere to rubber-coated or vinyl surfaces; not for Olympic barbells

Are there size or safety limits I should know about?

PlateMate donuts are intended for use on dumbbells 25 lb and heavier; do not use them on 20 lb or smaller dumbbells. The magnetic surface area measures roughly 4"×4", so ensure your dumbbell end provides that flat metal area for secure attachment. Always check attachment before lifting and avoid rapid impact or throwing the weights.

• Recommended for use with 25 lb dumbbells and up
• Require an approximate 4"×4" flat metal face for proper contact
• Inspect magnet grip before each set; avoid use on coated surfaces

Who is this for? Lifters who want fine-grained strength progression, home gym owners working with limited space, personal trainers guiding clients through gradual load increases, and anyone who prefers buying a few adjustable tools over a full dumbbell rack. If your equipment is compatible with a 4"×4" iron contact area and you need small, reliable weight jumps, PlateMate’s 1.25 lb donut pair offers an economical, space-saving solution.
