Rollerblind Chain Stop Clear
This is a stop for a roller blind. It clips on to the plastic chain which stops the chain going through the chain-control.
To install the stop pull down the roller blind to the desired height, reach up to the top ball on the chain where the chain as been going into the chain-control, pull down and hold on the ball because that is where you want to put the stop. Then pull the blind right up and then all the way down to check that the roller chain stop has been put in the right place.
