The fastener system is pre-assembled, the door hinge can be changed subsequently without having to remove any devices.
If no devices are installed in the door, there is no need for additional grounding.
If additional grounding is necessary, grounding straps must be used for degree of protection IP55 (see section "Accessories").
Apart from the standard espagnolette with 3 mm double-bit there are also twist lever catches, optionally with or without a lock. The twist lever catches must be ordered separately (see section "Accessories").
Inner door struts are optionally available for fastening cable ducts or devices to the inside of doors.
