Compatible with interior and exterior doors up to specified weight limits. Verify door width, thickness, and weight against manufacturer specifications. Check door frame construction can support mounting requirements.
3) How do you determine left hand vs right hand installation?
Stand on the pull side of the door. If hinges are on your right, it's right hand. If hinges are on your left, it's left hand. Order the appropriate hand for proper track arm operation.
