Frequently Asked Questions

Does this lock include the strike plate and handleset trim?

No, this is the lock only. The strike plate on the door jamb and handleset trim are sold separately.

Will standard trim work with this Marvin lock?

Only if your door is not pre-drilled. Marvin sliding doors have a unique 11-1/4 inch screw hole pattern that requires Marvin-specific trim.

How do I test the lock operation before installation?

Insert a screwdriver into the center lock, push the plate back, and test the thumb turn or key operation to ensure proper functionality.
