A relatively recent innovation in the design and construction of wall safes in recent years is the introduction of 1-hour fire resistant wall safes. The typical fire resistant wall safe has a much larger depth dimension than a traditional, non-fireproof wall safe. The extra wall depth is needed to accommodate the fire resistant material built into the walls of the body of the safe. Because of their relatively large depth dimension, fireproof wall safes should be installed in very deep walls or in a standard wall located in front of void space. It is important to note that installing a fire resistant wall safe tends to be more difficult and complex than installing a standard (non-fire) wall safe. For this reason, we recommend that wall safes of this type by installed by a licensed contractor or builder with the necessary installation expertise.
