The AP3 Padlock is designed for outdoor use on planet Earth, including in our cold environments. AP3 is rated for use to -30ºC. However, well the device works, it is still likely to accumulate ice and snow that can impede normal operation.
Please review this guide that shows the best practices for using AP3 in winter environments. Talk to our sales team (sales@sera4.com) if you are interested in buying protection sleeves for your padlocks as they are highly recommended.
