TRVL FIELDER Self-Adhesive Swivel Casters for Countertop Appliances, Set of 8 in White

A set of eight small swivel casters in white that stick beneath an appliance, a bin or a storage box and let it glide across a hard countertop instead of being lifted. Each caster turns through a full circle, so the load can be nudged sideways as easily as forward.

• Fitting: peel the backing, press each caster onto a clean flat underside, then let the bond cure for a day before putting weight on it. No drilling, and nothing is screwed into the appliance.
• Rated load: the two sources disagree. The specification panel states 18 lb, while the description claims 20 lb across four casters. Take the lower number as your working figure and add casters if the item is heavy.
• Build: ABS bodies with metal ball bearings, per the attribute panel.
• Surfaces: intended for hard, smooth tops. The maker advises against white quartz.
• Listed dimensions of 4 x 2 x 5 in describe the package, not a single caster; no individual caster height or plate diameter is published.
