Sturdy Built Demco-compatible Trailer Breakaway Cable 44" Length, 3/32" Steel with S-Hook for DA10/DA16/DA20/DA91

When towing, a properly functioning breakaway cable adds a critical layer of passive safety by engaging the actuator so hydraulic pressure reaches the trailer brakes during an accidental disconnect. This replacement cable is built to match Demco hydraulic surge actuators and provides the length, thickness, and attachment style needed to fit common Demco models. Use it to restore or upgrade the mechanical connection between trailer and tow vehicle so your surge brake actuator can operate as intended in an emergency.

How does this breakaway cable interact with a Demco surge actuator?

The cable links the trailer coupler to the tow vehicle so that if the coupler separates, the cable pulls a lever on the actuator to push hydraulic fluid into the trailer brakes. It is specifically sized to match Demco actuator linkages and the S-hook allows quick, reliable attachment to a hitch. Proper routing and secure attachment let the actuator perform as designed during a disconnect event.

• Direct mechanical connection to the actuator lever to initiate braking
• 3/32" cable thickness resists routine wear and abrasion
• 44" overall length accommodates common hitch and coupler distances
• S-hook design for straightforward hitch attachment without tools

Will this cable fit my Demco actuator model?

This assembly is crafted to be compatible with Demco DA10, DA16, DA20 and DA91 hydraulic surge brake actuators. Check your actuator model stamping or documentation to confirm compatibility before purchasing. If your actuator is one of the listed models, this cable will provide the correct length and hook style to connect properly.

• Fits Demco models: DA10, DA16, DA20, DA91
• Designed to match factory-style attachment points and throw
• Ideal for replacing worn or missing breakaway cables on these actuators

What are the physical specs and installation details?

The cable measures 44 inches end-to-end with a 3/32-inch steel cable core that balances flexibility with tensile security. An S-hook on one end is made to attach to the tow vehicle hitch; the opposite end secures to the actuator lever per Demco's installation orientation. Installation requires routing the cable to avoid kinks and interference, and fastening the hook so normal coupling does not create tension.

• Overall length: 44 inches for adequate reach and safe routing
• Cable diameter: 3/32" for reliable pull strength and flexibility
• S-hook allows quick hitch attachment; follow actuator instructions for correct hook placement
• Inspect routing for chafing and secure fasteners after installation

How should I maintain or inspect this breakaway cable?

Regular visual checks keep the breakaway cable dependable: look for fraying, corrosion, bent hooks, or reduced movement. Replace the cable immediately if you spot wear or deformation. Proper storage and periodic lubrication of adjacent moving parts will prolong service life.

• Inspect cable and hook before each towing trip for frays or rust
• Replace at first sign of damage; do not attempt field repairs
• Route to avoid sharp edges and heat sources that accelerate degradation

Who is this for: This Sturdy Built replacement is aimed at trailer owners, fleet managers, and service shops using Demco DA10, DA16, DA20, or DA91 hydraulic surge actuators who need a factory-style breakaway cable. It suits anyone replacing a missing or worn cable, performing routine safety maintenance, or prepping a trailer for safe towing where reliable actuator engagement is required.
