Roller blind mechanism for 45mm tube, chain operated. You get the control end & idle end & metal fixing brackets which you can top or face fit. Made in the U.K.
NB size refers to the external diameter of the metal roller tube
Comes with either a never ending chain.
The chain drop is how far the chain loop extends down from the blind, and is therefore approximately twice the total length of the chain.
For example, a 1,000mm drop chain contains around 2,000mm of total chain.
You will get a free safety device with each roller kit, which must be used.
All continuous chains must be secured using a chain tensioning device which must be fixed to a wall at least 1.5m above the floor.
To calculate maximum allowable chain length to comply with new safety regulations:
Max drop of chain = (Height of rail from floor in cm - 150cm)
MUST BE FITTED WITH A SAFETY DEVICE
This video shows you how to reinstall a chain into the control end of a Louvolite roller blind. Whilst the video uses a 32mm sidewinder instead of a 45mm sidewinder, the process is very similar.
