Cash ratings

All cash ratings quoted are the manufacturers recommended cash ratings.

Cash rating is the amount of cash for which an insurance company will offer overnight cover.

The actual amount of cover can vary between insurance companies and locations and may be higher or lower than recommended rating.

If this is important to you, you should check what cover your insurance company will offer. The recommended rating is on the basis that the product is installed according to the manufacturers instructions.

FireResistance

Fire resistance is usually measured by the number of minutes a safe or cabinet has been tested to protect its contents when exposed to fire.

The longer the period in minutes, the greater the fire resistance offered. This rating is normally obtained by measuring the internal temperature of the safe whilst being exposed to temperatures around 1,000 C in a furnace.

The critical temperature before paper records char or combust is about 177 C. Computer media cabinets, however, are tested to maintain internal temperatures below approximately 52 C - which is the maximum temperature most media manufacturers recommend.
