TriMark Model 030-0900 RV Entry Door Lock

This lock has many variations. They all look the same installed, but depending on how thick the door is and how far away from the edge of the door the lock sits - the deadbolt and the inner mechanisms change. The lock needs to be removed to look for a part number. The number is located on the back side of the interior handle (red circles): Notice the paten numbers (not needed) and the return spring. The return spring attaches to the actuator plate. The 5 digit number along with a 3 digit production code should be on it. On the long deadbolt (2 inch) the number is stamped on the head of the rivet the holds the latching rod. If you need help email us pictures of the back side of the interior handle to rvparts@rvpartscenter.com
