The SDTRINV1024 is a symmetrical electric strike with stationary contact (2 times) invisible and with release lever. The CDVI S series strikes offer a solution for the vast majority of applications required by the market. The strikes have a symmetrical shape which makes them reversible and can therefore be used for both left and right hand doors. The adjustable strike allows the lock to be adapted to almost any door. All strikes are equipped with a varistor, which provides protection against the self-effect. By using a varistor, it is not necessary to use a diode, the strikes can be connected to AC and DC and are independent of polarity. The combination of all these features means that with the S series you have a solution for every situation.
