An overrun brake coupling damper is used on trailers, caravans, boat trailers, horse trailers, and folding trailers to regulate braking by absorbing shock when the trailer overruns the towing vehicle during sudden stops. It acts as a shock absorber, ensuring smooth and safe braking.

Key applications include:

• Trailer towing: Common in medium-weight trailers for recreational activities.
• Rental trailers: Provides reliable braking for frequently used rental options.
• Marine applications: Ideal for boat trailers, safeguarding against water exposure.
• Heavy-duty trailers: Essential for controlled braking in heavier trailers.
