Reviews
The electrical cupboard sign we bought looks clean and professional, and the message is clear: electrical hazard and restricted access. We put it on the utility cupboard door in our office. My only note would be: if you mount the sign too low or partly behind equipment (e.g. cables, boxes), people might not see it until too late. Best to place it at eye-level and in a clear spot so the warning is obvious.
We used this sign in our small warehouse in West Bromwich. It’s clear and easy to read — hazard icon works well. However, when I handled it before fixing, the material felt a bit lighter and thinner than I expected compared with other signs I’ve used (e.g. aluminium or thicker plastic). That said, once mounted it looks fine. For an internal cupboard or low-impact environment it’s a decent value.
I ordered this sign for our small manufacturing workshop’s electrical cupboard. It arrived quickly, and installation was straightforward: we cleaned the surface and used the adhesive backing - the sign stuck firm. The black/yellow hazard symbol is unmistakable and the extra instruction helps reinforce “do not store stuff in here - only for electrical gear.” Very pleased with the quality and clarity.
We fitted this “Electrical Cupboard” sign on the metal door of our maintenance room in Dudley. The size (we chose 300 × 200 mm) is perfect - big enough to notice at a glance but not oversized. The sign looks professional and heavy-duty enough for both indoor and occasional outdoor conditions (door sometimes exposed when open). For any workshop or communal building, this sign is a useful safety addition.
