Wobbly curtain-rod brackets? Check wall fixings and load limits
Curtain-rod brackets need fasteners matched to the wall or ceiling. Remove the curtain before checking a loose bracket, and do not drill where concealed services are uncertain.
IKEA's BETYDLIG bracket requires separate fasteners suited to the wall or ceiling; its fixing screws and wall plugs are not included. Load ratings depend on bracket spacing and how curtain weight is distributed.
