Installation Height

Vertical Blinds

Under the BS EN 13120 Child Safety Standard, installation height is used to calculate the maximum allowed chain/cord lengths and is defined as the distance from the top of the blind to the floor when fitted. The maximum length of control chains and cords depends on whether the installation height is known or unknown and the child safety components used for each type of blind.

Vertical Blinds with standard wand control

If using our standard wand control the blind will be inherently child-safe as it contains no control chains or cords.

Vertical Blinds with optional cord & chain

Installation height known - maximum cord/chain length will be installation height less 150cm
Installation height unknown - maximum cord/chain length will be 100cm
