Polished Steel has a brighter, more reflective appearance, while Satin Steel provides a softer sheen. This choice makes it easier to coordinate the sign with other steel-finished ironmongery in the surrounding space.\u003c\/p\u003e\u003cp\u003eThe sign is listed with a 76 mm backplate dimension. When selecting it, consider both the preferred finish and the available area on the door. The engraved “Fire Door Keep Locked” message identifies the instruction clearly, while the compact backplate keeps the presentation concise. As this is an engraved door sign rather than a locking device, any lock or other functional door hardware required must be selected separately.\u003c\/p\u003e","products":[{"product_id":"mm-steel-line-fire-door-keep-locked-engraving","title":"Steel Line - Fire Door Keep Locked Engraving","description":"\u003cp\u003eThe Steel Line Fire Door Keep Locked Engraving is an engraved sign for fire doors that indicates a keep‑locked door.
