What to know before buying
Listing details to confirm
The listing is inconsistent about dimensions: the title and size feature give 22 x 22 x 8, while the dimensions field says 8"D x 22"W x 8"H. It also calls the product 304 stainless steel in the title but lists only Stainless Steel as the material. IP66 and explosion-proof language are listing claims, and the supplied details do not substantiate what standards or use conditions those claims cover. Confirm the selected listing's exact dimensions, steel grade and suitability for the intended installation.
