Is Demco Hydraulic Brake Actuator DM8759432 Bolt-On or Weld-On

Question

Question:

Is Item # DM8759432 bolt on or weld on? # DM8759432 is pictured without any provisions, e.g tabs, for bolting on but the description says bolt-on. Also, what is the minimum tongue length that this would fit on? As pictured would this actuator be compatible with mounting on this?

While we do have a bolt-on option, the Demco Hydraulic Brake Actuator - Drum - Primed - 12" Adjustable Channel Down - 8,000 lbs # DM8759432 is actually a weld-on actuator. If you are looking for a bolt-on option, there are a couple similar options:

- Demco Hydraulic Brake Actuator - Drum - Zinc - 12" Adjustable Channel Center - 8,000 lbs # DM8758521

- Demco Hydraulic Brake Actuator - Drum - Zinc - 8" Adjustable Channel Down - 8,000 lbs # DM8759231

Your 11 inch channel is more than long enough, as each of these will very easily fit that length, including the weld-on actuator # DM8759432.

The only other thing you may need if you don't have one is a coupler like the Demco Trailer Coupler - 2" Ball # DM12688-95 or 2-5/16" Ball # DM15791-97.
