Multifunctional Dog Car Seat Belt - Two buckles and dual-bolt hook: This belt is designed with two different types of buckles and a dual-bolt hook. One buckle attaches to the standard seat belt buckle, like a typical human seat belt. The other hook latch connects to the point between a child seat and the car trunk. You can choose the buckle you need for your vehicle and setup. - Adjustable and reflective design: The strap length is adjustable from 24.8 inches to 35.4 inches, allowing your pet to move within a defined space. Made from sturdy nylon fabric with reflective threads for improved visibility and safety during night use. - Elastic buffer protection: An elastic buffer design helps absorb shocks from sudden braking or sharp turns, protecting your pet and helping reduce driver distraction during travel. - Universal fitting: The seatbelt clip tab is 0.83 inch wide, compatible with most vehicles. Please check your buckle size and compatibility before ordering. 2-3 practical use scenarios - Daily car rides: Use in the back seat to keep a small to medium dog secure and comfortable, reducing movement and driver distraction during routine trips. - Travel with child seats or irregular layouts: The dual-buckle and hook options allow flexible mounting when a child seat is installed or when a trunk-area connection is preferable, making it easy to adapt to different vehicle configurations. - Night or low-light driving: The reflective threads enhance visibility, helping to alert others to the presence of your pet in low-light conditions.
