Pull-Out light shelf for Furman power conditioner PL-8 series II

This shelf is designed to rest on the pull-out lights of a Furman rack-mounted power conditioner PL-8 series II, a popular type of power source for audio production racks. Other Furman power conditioners (and the current PL-8C model) have similar pull-out lights but I have not verified the dimensions of the other model's light tubes or their spacing.

I have included little slots in the legs that wrap around the tubes for inserting a stick or zip tie to secure the shelf to the power condition
