The Wall Safe M83<\/strong> is designed for users who need a high-capacity in-wall safe that remains completely discreet once installed. Built for residential and professional environments, it provides secure day-to-day protection for valuables, cash, and important documents while taking advantage of unused wall space.<\/p>\n Thanks to its in-wall installation, the safe benefits from both concealment<\/strong> and structural anchoring<\/strong>, making it significantly harder to locate and remove than freestanding units. The M83 is a strong choice for homes, offices, private rooms, and any setting where security must remain out of sight.<\/p>\n The Wall Safe M83<\/strong> is supplied as standard with a twin-key locking system<\/strong> (two independent key locks) to increase resistance and provide redundancy for everyday use.<\/p>\n For users who require enhanced access control or convenience, the locking configuration can be upgraded with:<\/p>\n The safe is manufactured from high-resistance sheet steel<\/strong> and engineered for reliable protection in demanding everyday conditions. The locking system uses solid steel locking bars and reinforced hinge geometry, designed to reduce vulnerability to forced attacks and tampering attempts.<\/p>\n This model is especially suitable when you want a safe that offers capacity<\/strong> without sacrificing discretion<\/strong>\u2014ideal for clients who prefer hidden security rather than visible deterrence.<\/p>\n For best performance, install the safe embedded into a properly prepared masonry bed (typically concrete). A correct installation improves stability, reduces movement under attack, and helps preserve long-term lock reliability. If installed on an exterior-facing wall, appropriate insulation and sealing are recommended to mitigate humidity and thermal bridging.<\/p>\n Yes. Its high capacity and discreet installation make it ideal for storing passports, documents, jewellery, and emergency cash in residential environments.<\/p>\n It should be installed in a structurally suitable wall (masonry or reinforced partition). We recommend assessment by a qualified installer to confirm depth, reinforcement, and correct bedding.<\/p>\n Wall safes are secured through embedding into the wall structure. Proper bedding and sealing are essential to ensure the safe cannot be extracted or loosened.<\/p>\n Lock upgrades are possible depending on configuration. Any change should be carried out by qualified technicians to ensure correct fitting and reliability.<\/p>\n The key advantage is capacity<\/strong>. With 113.1 litres of internal volume, it offers significantly more space for document folders, cases, and bulk valuables while remaining fully hidden.<\/p>\n Explore related categories:<\/strong> Wall Safes<\/strong><\/a> | Safes<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":" The Wall Safe M83<\/strong> is a high-capacity in-wall safe (113.1 L, 97 kg) with standard twin-key locking, designed for discreet installation in homes and offices to protect valuables and documents while remaining completely hidden.<\/p>\n","protected":false},"featured_media":518495,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[2662],"product_tag":[],"class_list":{"0":"post-19216","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-wall-safes","8":"first","9":"instock","10":"taxable","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/product\/19216","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":0,"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/product\/19216\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/media\/518495"}],"wp:attachment":[{"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/media?parent=19216"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/product_brand?post=19216"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/product_cat?post=19216"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/arcasgruber.com\/en\/wp-json\/wp\/v2\/product_tag?post=19216"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Technical Specifications<\/h3>\n
