Compatibility Of Demco Hydraulic Brake Actuator with Lunette Ring and Reverse Lockout


Dear Sir/Madam, Could you please confirm if this model would work with a 4600 lbs trailer and also can we use Demco Lunette Ring - DM09557-97? and manual reverse lockout DM5939 is usable with this? Please confirm same..


Expert Reply:

The Demco Hydraulic Brake Actuator, Drum, Black, 8 Inch Adjustable Channel # DM8759122-30 that you referenced is designed for trailers weighing up to 8,000 pounds with 800 pound tongue weights. This brake actuator will work well for your 4,600 pound trailer.

The # DM8759122-30 has a 3 inch wide channel on the front, and the Demco Lunette Ring # DM09557-97 is designed to mount in a 3 inch wide channel, so it will work well for you on the Demco # DM8759122-30 actuator. This # DM09557-97 lunette ring has an inner diameter of 3 inches and an outer diameter of 6 inches.

The Demco manual Reverse Lockout Kit # DM5939 is designed to work with the # DM8759122-30 actuator and will work well for you.
