No; the Demco Hydraulic Trailer Brake Actuator # DM72VR is designed for use with free-backing brake systems and does not have a lockout feature- so you wouldn't be able to use the Manual Reverse Lockout Kit # DM5939 with that actuator.

To use the Manual Reverse Lockout Kit you would need an actuator like the Demco Hydraulic Brake Actuator w/Manual Lockout # DM8760011 . This kit requires 1/2" x 4-1/2" Grade 5 bolts (not included) for mounting as well as a coupler similar to # CT-5003-Z depending on your hitch ball size.

Hi Jason, We do have a reverse lockout (and cover!) you can use with the Demco Hydraulic Brake Actuator w/ Drop #DM8758811, which is the Reverse Lockout Solenoid #DM11993 and Cover #DM11674-95. Another option - if you don't have the actuator yet…
