Door Thickness Tips

The first thing you want to know before buying a Smart lock is what kind of door the lock will be installed on. Door thickness does range from how old the door is, what kind of wood has been used, or the use of other materials like metal. 

Standard door thickness sold at most home improvement stores is going to be 35mm thick. Taller doors can have up to a thickness of 45mm thickness. Anything over 45mm is considered to be a thick door which could make it incompatible with some smart locks on the market. 

To measure the door thickness, take a ruler and start at the vertical edge of the door, cross the ruler over the deadbolt faceplate, to the opposite edge of the door. Keep the measurement handy as you will want to reference it with the specifications of these thick door-compatible smart locks.

Conclusion

There are many Smart Locks on the market today because of the advancements in security technology. Knowing the compatibility of the lock and door thickness is very important to make sure that your lock fits securely and cant be accessed by anyone else but you or approved people. Make sure to take measurements of your door first and then find the most compatible Smart Lock for what you need.
