1. CABLE DUCT PROTECTION: Speed bumps are used to regulate traffic speed and feature two integrated channels to protect cables from damage caused by pedestrian and vehicle traffic. 2. PRODUCT MATERIAL: Made of rubber material. The thickened rubber makes the structure of the speed bump firmer and more stable, does not deform under pressure, instantly returns to a stable state, is odorless, and does not fade. 3. SAFETY DESIGN: This speed bump is made of rubber, and the cable ramp protection features raised dots and textured stripes on the surface to ensure safe vehicle passage. The bottom shock absorption can control speed without damaging the car or the road. 4. REFLECTIVE DESIGN: The speed bumps are black and yellow for visibility. They attract drivers' attention both during the day and at night, thereby reducing vehicle speed and enhancing safety for drivers and pedestrians.
