Better airflow for your dog.

A simple way to give your pet the ventilation they need.

The AK-9 Vent Lock provides a secure link between your boot lid and the boot lock, holding it open just enough to let air flow through — and it also works on the rear door and frame of 4-wheel-drive vehicles. It works best with a sunroof or one side window cracked open, so warm air rises out while cooler, fresher air is drawn in through the boot.

It's quick and secure to fit, and it fits 99% of vehicles. Four sizes let you choose how much you open the gap, from a modest 2in opening up to a generous 12in, depending on your car and the conditions.

⚠ Safety: A vent lock improves airflow but does not make a parked car safe in warm weather. Never leave a dog alone in a vehicle on a warm day — temperatures can rise dangerously fast.

Will it fit my car? +

It fits 99% of vehicles, and also works on the rear door and frame of 4-wheel-drive vehicles.

Open a sunroof or one side window a little so warm air rises out while cooler air is drawn in through the boot.

How does it work? +

It forms a secure link between the boot lid and boot lock to hold it ajar for airflow. Opening a sunroof or window a little helps warm air rise out while cooler air is drawn in.

Which size should I choose? +

Smaller openings for cooler days, larger for warmer conditions — but airflow alone is never a substitute for not leaving a dog in a warm car.

No — it improves airflow but never makes a parked car safe in warm weather. Never leave a dog alone in a vehicle on a warm day.
