10 Roller blind chain stop lock ballsFits all roller chains with 4.5mm diameter balls
STOPS BLIND GOING UP OR DOWN TOO FAR
You can position these on your roller blind chains to stop the blind in the desired position without going to far. If your chain allows you can fit one to stop the blind going up too far and another one to stop the blind coming down too far.
Simply snaps over chain balls.
The drop of the blind and blind chain may prevent you being able to have two stop lock balls on roller chain.
