138.13: Electric Strike with adjustment Profix

Fail unlocked electric strike, the 138.13 are indicated to install interior doors, this electric strike has a compact design and radius keep. 
Until now, a cut-out was needed in door profiles to accommodate the electric strike swing, now with the combinatation of the adjustment Profix2 and the radius keep, the cut-out of the profile is no required. 
With 138.13 the door seal is unaffected. Besides the door being more visually appealing, the seal in the frame is no longer interrupted. The door seal surface thus remains intact.
