This appears to be a new unused panel. It was given to me, but I don't have need for a strip of 20 Amp outlets in my shop and I don't have a rack-mount computer setup.
The specs are as follows:
Product Type: Power Strip
Receptacles: 8 x NEMA 5-15R
Cord: 15 ft long, 12/3 (12-AWG, 3-conductor)
Plug/Connector Type: NEMA L5-20P Twist Lock
Receptacles Spacing: 3"
Circuit breaker to protect circuit from overload

Please see the photos to check condition.

I did notice that the back panel has a slight bulge to it. I checked inside, and this is because the internal wire is stiff and the wiring to the indicator light and the reset switch isn't nesting as cleanly as it could with the wiring to the receptacles in that area. The back panel isn't very stiff compared to the rest of the box and the internal wiring, so it's the back panel that is flexing a bit. There is no defect or damage there, and the remedy if desired would be to adjust the way the wires nest internally.

These are available on line at prices that range from $225 to $285. I'm asking $120 (plus shipping). This will ship Priority Mail, insured. I normally ship within the 1st business day after receipt of PayPal payment.
