Frequently Asked Questions
Are these CAP coated hex dumbbells suitable for apartment living?
Yes — coated hex dumbbells are among the more apartment-friendly iron options because the coating dampens sound and hex or 12-sided ends prevent rolling. Still, always use a thick rubber mat, avoid dropping heavy weights, and place them away from shared walls to minimize disturbance.
How do I reduce the rubber smell when they arrive?
Air them outside or in a well-ventilated garage for 48–72 hours if possible. Wipe heads and handles with a mix of mild dish soap and water, then dry thoroughly. Odor typically fades with time; ventilation speeds the process.
Do these dumbbells come in pairs or single units?
All three listings are sold individually. If you need a matched pair, order two of the same weight. Check the product page for the seller’s details and any bundle options that might be available.
