About this item

  • ONE PAIR FROM WARM-UP TO WORKING SETS — 10 weight levels from 5 to 50 lbs per dumbbell cover the full range from warm-up sets to your heaviest working sets — enough to program a full push, pull, or leg session on one pair. One adjustable weight set replaces a shelf of ten fixed dumbbells, so the training corner stays clear. Whether you're building a home gym from scratch or adding heavier options to your current setup, this adjustable pair is the right pick for both.
  • ONE-HAND, ONE-SECOND WEIGHT CHANGE — Seat the dumbbell in its tray, rotate the 33 mm ergonomic handle once and the next weight is loaded — no side dials, no plate swapping, no tools. Adjustable weights ready between every set — about a second, so heart rate and rest intervals stay under your control. 10 levels dialed in: 5.5 / 11 / 15 / 21 / 25 / 31 / 35 / 41 / 45 / 50 lbs.
  • SOUND AND SIGHT CONFIRM EVERY LOCK — Twist the handle once — in about a second — and hear a distinct click as the twist-lock collar engages the loaded plates. The current weight aligns with the orange indicator right on the handle — no guessing between sets. Built to hold through 10,000+ raise-and-lower cycles of overhead dumbbell pressing and heavy dumbbell rows.
  • ENGINEERED ENGAGEMENT — THE TRAY IS PART OF THE MECHANISM — A raised pin on the underside of each dumbbell end mates precisely with a molded catch inside the storage tray. The handle only rotates once these two engage — not when the dumbbell rests on a shelf, a bench, or the floor. This engineered engagement keeps weights locked mid-lift, from your first lift to your last — no accidental release.
  • STEEL CORE, NYLON SHELL — QUIET AND ODOR-FREE — Each weight plate is a solid steel disc wrapped in a high-quality nylon shell, and the rubber-coated handle keeps a firm grip even during sweaty sets. The nylon dampens the impact when a dumbbell is set down on the base, keeping the sound low enough for early-morning or late-night sessions in a shared apartment. The coating stays odor-free after weeks of use, and cushions the base so it rests on hardwood or tile without denting the floor.
  • ONE TRAY PER DUMBBELL — Each dumbbell comes with a matching storage tray, giving your weights a dedicated home right out of the box. 10 molded slots cradle each weight plate inside the tray, and the V-shaped center slot guides the handle back to seat as you set it down — no rolling off the bench, no plates scattered across the floor between sets.
  • ONE SQUARE FOOT PER DUMBBELL — TUCKED AWAY WHEN YOU'RE DONE — Each dumbbell with its storage tray measures 18.11 × 8.27 × 7.48 inches, taking up about one square foot of floor space. Slide the pair under a bench, into a closet corner, or beside a squat rack when the session's over. Every piece — dumbbells, plates, handles, and trays — is covered by a full 10-year product warranty.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

Why did my order arrive in separate packages?


Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.
