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 the option of 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 chain, 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.
