Bit more info below about the mystical Gem safe that didnt exsist !

In 1970, SLS introduced their famous ‘Bankers’ range, incorporating more barrier materials and utilising refractory waste, which were a direct challenge to Chubb’s famous TDR (Torch and Drill Resistant barrier) safes.


By this time SLS safes were being exported across the globe, in vast numbers, particularly the USA, where SLS are still regarded as one of the finest safe manufacturers to this day.


In 1972 SLS became part of the Mather and Platt group, a specialist foundry, casting and engineering company based in Manchester. This meant access to a wider range of facilities and use of alloys and ceramic aggregates.



The carcass castings were made at The Park Foundry in Manchester, and then transported to Telford to be made into safes. During this period the SLS team came up with a method of suspending ceramic nuggets in an alloy casting, to achieve the ultimate anti-drill, anti thermal lance barrier, which led to the development of the famous ‘Gem Anti-Lance Safe’. It was considered by many, to be the finest safe in the world, offering protection at least twelve times greater than any other Bankers safe. It was independently tested by the ‘Underwriters Laboratory Inc’ in Chicago against torch, tool and explosive attack, achieving in excess of US UL TX TL60, by a substantial margin of protection.
