RK12WALHM - Top Cable Entry Brush

Hi,

I have purchased the above wall mounted rack and the cables will be entering the rack from the top utilising the 2 provided cable entry slots.

However, once the blanking plates are moved to allow the cables to enter there is a significant amount of space for dust ingress etc, not to mention issues with cooling.

Looking around it does not appear that Startech provide a custom brush but has anyone found a 3rd party one or universal one that will fit??

Regards
Steve
