Lit Cabinet Signs are ridged signs built as a rectangle or a simple shape, they are different from a Lit Shaped Sign in the way they are constructed. The most unique feature of a Cabinet sign is the Sign Face Retainer. This is a metal piece that is fabricated to the profile of the sign. The metal retainer holds the sign face securely on the sign. This allows the sign to be built much larger due to the face not being held with a trim that is glued to the face. The Cabinet signs are also built of thicker metal and built structurally strong.
