List of Recommended Substitute Products
: The actuator on the D4D-N is a non-safety type. The D4N is recommended for safety applications (form lock type). Be sure to mount it cor-
rectly.
: M screws are recommended to comply with European standards. Therefore, the M20 type is recommended as a substitute when the PG13.5
conduit-type is not available in a D4N model.
