The specification of our Superior Mirrors for Training 

Arena Mirrors are very high quality 6mm safety backed to British Standard (this safety backing ensures that no large shards of glass come away should the mirror have an impact). They are a generous size 2440 x 1220 (8ft x 4ft)

TOTAL THICKNESS 23mm  

Our arena mirrors are encased within sealed within a tough galvanised framed unit on sides and the back of the mirror preventing water ingress and have an impact layer 12mm (absorbing any shock, this prevents breakages, flex and distortion)
