3M Reflective Film Iron Truck Mounted Attenuator
The RMHs Retractable Vehicle Rear Safety Protection Device is an advanced driver protection system designed to prevent rear-end collisions. Installed at the rear of trucks, this truck mounted attenuator features high-visibility red and white reflective film that provides clear warning signals to following drivers. In the event of a rear-end collision, it effectively reduces impact forces and prevents smaller vehicles from sliding underneath the truck, significantly enhancing driver and vehicle safety.
Without proper protection, rear-end collisions can cause smaller vehicles to become trapped underneath trucks, leading to severe accidents and serious injuries. The RMHs anti-collision barrier extends to create a protective buffer that cushions impact while preventing dangerous underride scenarios.

Frequently Asked Questions
What is the purpose of this product?
It is mainly used to prevent small cars from sliding under trucks during rear-end collisions, while also absorbing impact force to reduce accident injuries.
Can it really prevent underride accidents?
Yes. Its installation height (about 1 meter) is designed to block the front end of small cars (70-80 cm tall), ensuring that the impact occurs at the sturdier engine compartment of the car.
Will it affect daily driving?
No. It can be fully retracted during normal driving, adding no extra length to the vehicle. It should only be deployed when parked for maintenance or loading/unloading.
Which vehicles is it suitable for?
It is suitable for trucks, pickups, trailers, etc., with a total weight of 2-4 tons. Before purchasing, you can provide your vehicle model information for compatibility confirmation.
Does it require professional installation?
Professional installation by a repair shop is recommended. It must be securely mounted to the main frame at the rear of the vehicle to ensure safety and reliability.
Can it be customized?
Yes. Customization of dimensions and colors is supported, such as matching the unified branding colors of a fleet.
Is it durable?
Yes. The main body is made of channel steel and stainless steel, with an electrostatic coating for rust prevention. Aluminum alloy components are responsible for buffering and absorbing energy.
What are the benefits besides safety?
• Reduces accident compensation and repair costs.
• Enhances the professional image of the fleet.
• Some insurance companies offer premium discounts for vehicles equipped with safety devices.
Summary: This anti-collision barrier is an essential "safety trunk" for trucks—stored out of the way when not needed, but life-saving when deployed.
