From 3 Monkeys:

"Now you can make your DC cables the perfect length from your power supply to your effects pedals. True freedom from the currently bundled, cheap plastic DC power plugs and cable. We invented the Solderless 2.1mm DC connector and we patented it.

Our standard low-capacitance (28-30pF/Foot), audiophile-grade cable is .120” in diameter (so it will bend at 90º easier) and formable for precise cable routing and a clean look. 

Can be used with your Voodoo Lab Pedal Power and ISO 5, Strymon Zuma and Ojai, MXR DC Brick and Iso-Brick, T-Rex Fuel Tank, Pedaltrain Powertrain, Pigtronix Power, Truetone 1 Spot Pro, and other popular effects power supply units."
