This is our patented dual voltage solenoid we have been using for the past few years. You can use this solenoid in our ND80 kit modifications as well as in our MARRAY GN series and Cal-Royal modified locks. The solenoid is 12 and 24 volt, as well as switchable from Fail Safe to Fail Secure or in reverse to Fail Safe. You can click here to go to our video turorials and view a video on how to replace the solenoid. You can click here to go to our literature page and open up a PDF instruction document as well. 

This solenoid is also used in our Sargent ET trim modifications, as well as in our Von Duprin 33 series trim modifications. You would need to chose the correct product above, since the cam is different for each of these products, even thought the basic solenoid is the same.
