Assigned to SEWOSY electric strikes, this brand denotes two benefits:

- the adjustable roller of the latch, enabling to fit the electric strike to various configurations,
- the reduced aperture offset, which often avoids the lateral cut of the door frame, requiring less space to rotate on itself.


This designation applies to most SEWOSY electromagnetic locks, providing great flexibility to the installation thanks to a wide choice of bespoke accessories. Including an anti-remanence system by ejector, the VELMAG™ locks are instantly unlocked when power off. Manufactured according to the E-PLATES technology, they have a better magnetic performance, which optimizes locking efficiency.


This brand name corresponds to all SEWOSY aluminium housings. The CPREG® housing counterplate can be fitted in case of door sagging through a sliding system.
