Supporting Heavy Virtual Dynamics Power Cords

Hi Folks,
As much as I like the Power Cords from Virtual Dynamics, the weight and loose fitting female end of the cables does present a bit of a problem. Currently I put a sponge ball between the rack shelf and the power cord near the connection to the device. In essence one for the CPD, one for AMP and one for the PRE. Just wondered how some of you are compensating for power cords that do not fit snug into the back of devices. Other than that the cables are great (using Masters LE 2.0 Power Cords).
