Over the past month we have been adding chokes to our website. EDCOR is now manufacturing two series, the CXC and XC series. The XC series are the smaller of the two series and are open frame and are channel mounted. The CXC are the larger of the two series and come with end bells. The values we have come up with for our series are from what customers have asked for. EDCOR will be adding new models when they become available. If you have any questions, or wish to have a custom choke made, please contact us.
