Leviton Non-Grounding Cube Adapter, 125 V, 15 A, 3 Outlet, 531-I, Ivory

Bottom line: The Leviton Non-Grounding Cube Adapter ($6.55 on Amazon as of 2026-10-06): Turns one non-grounded outlet into 3 NEMA 1-15R receptacles; main trade-off: non-grounding 2-wire design, so 3-prong grounded plugs will not fit.

SpecPicks Verdict

SpecPicks scored Leviton Non-Grounding Cube Adapter using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Leviton's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
