What Parts Do I Need to Repair a Roller Blind?
Most roller blinds can be repaired without replacing the complete blind. The part you need will depend on whether your blind is operated by a chain, internal spring or motor, and which component has become worn, damaged or stopped working.
Common replacement roller blind parts include sidewinder mechanisms, operating chains, spring mechanisms, brackets, idle-end plugs, roller tubes, bottom bars and replacement roller blind fabric. Individual components can often be replaced while keeping the existing blind, tube or fabric.
If you are replacing a mechanism, it is important to check the diameter and type of your roller blind tube before ordering, as mechanisms and fittings are available for different tube sizes.
