Short runs of flexible power cord?

I have had to put objects, such as wood boxes, bricks, VPI Bricks and books near the connector to relieve tension at the connection point. I have also attached string to the connector and attached the string to the wall with a screw at the outlet. I have also used Velcro ties to secure the cable to the equipment rack. This works well in rack mounted equipment.
Heavy cords can be a problem.
I do not re-call ever seeing a power cord shorter than 1 meter.

I've been dressing power cords since the day they got big.

Mapleshade has some very flexible power cords. They can custom make a short run as well.

I bought two 3' Audience PowerChords on Audiogon during the past year.
