Round-Edge Rubber Hex Dumbbell Rounded Corner Gym Dumbbell PROESCE LKDB-727

Product Features And Advantages：

The LKDB-727 round-edge rubber hex dumbbell is a classic free-weight tool built for gyms, strength training and home fitness, featuring a round-edge design. It uses a cast iron core—dense, accurately weighted and dimensionally stable—coated in EPDM rubber granules (black base with colored speckles) that are non-slip, wear-resistant, eco-friendly and odor-free; the handle is steel chrome knurled for a non-slip, rust-resistant, solid grip. The round-edge design softens the hex corners so drops don’t scratch floors or damage equipment, feel safer and look more refined, distinct from ordinary sharp-corner hex dumbbells. Weight ranges: 1-10kg in 1kg steps (1/2/3…/10kg); 12.5-25kg in 2.5kg steps (12.5/15/17.5/20/22.5/25kg). The hex shape won’t roll and can sit directly on the floor or a rack; the ends are stamped with clear weight markings. Weight, color and LOGO customization are supported. A dumbbell for every level.

Frequently Asked Questions：

I.Selection

Q: Who is this round-edge hex dumbbell suitable for?
A: This round-edge rubber hex dumbbell suits gyms, strength trainers, home fitness users and rehab clients for full-body strength training, upper/lower body and core work, free-weight and functional training. Weights run from 1kg to 25kg, so beginners, women and advanced lifters can all find the right load.

II.Material

Q: What is the dumbbell made of? What are the benefits of the round-edge design?
A: It uses a cast iron core coated in EPDM rubber granules (black base with colored speckles), with a steel chrome knurled handle. The round-edge design (rounded edge) softens the hex corners so drops don’t scratch floors or damage equipment, feel safer to handle and look more refined—distinct from ordinary sharp-corner hex dumbbells. The EPDM rubber granule coating is non-slip, wear-resistant, eco-friendly and odor-free.

III. Specification

Q: What weight ranges are available? Which are existing molds?
A: Weight ranges come in two levels: 1-10kg in 1kg steps (1/2/3…/10kg); 12.5-25kg in 2.5kg steps (12.5/15/17.5/20/22.5/25kg). The hex ends are stamped with clear weight markings for paired display.

IV. Usage

Q: What should I pay attention to when using the round-edge dumbbell?
A: Choose a weight suited to your goal and grip it firmly before starting; the hex shape won’t roll, and the round edges make drops quieter and easier on floors. Avoid dropping it—while the EPDM coating and rounded edges cushion impact, long-term dropping accelerates aging; keep hands dry for a better grip.

V.Customization

Q: Do you support weight, color and LOGO customization?
A: Yes. Weights from 1kg to 25kg are available, and EPDM color ratio, stamping and branding can be customized. MOQ and process details are negotiable, suitable for gym fit-outs, rack sets and brand retail.

VI.Sample

Q: Can I order samples for inspection?
A: Yes. Samples of different weights are available for you to verify the cast iron weighting, EPDM speckled finish, round-edge craftsmanship, chrome handle and weight stamping. Sample unit price, freight and lead time are quoted separately.

VII. Packaging

Q: How are the dumbbells packaged for shipping?
A: Dumbbells are packed as pairs or singles by weight range into export cartons / wooden pallets; carton/pallet counts, carton size and container loading can be quoted by weight range and order volume, suitable for ocean shipping, gym set purchases and retail warehousing.

VIII. Maintenance & Care

Q: How do I clean and care for the dumbbell?
A: Wipe the handle and rubber with a dry or damp cloth and keep them dry; avoid solvents and acids/alkalis to prevent EPDM aging and handle rust. Store long-term in a dry, ventilated place out of direct sunlight and high heat; periodically check for rubber cracking, round-edge damage and handle loosening.
