What Is a Cremone Bolt?
It's a type of locking mechanism typically used on double doors, which consists of a vertical rod that slides up and down into a strike plate. The rod is operated by a set of handles located at the top and bottom of the door. This design provides more stability and security than a standard latch bolt since it runs along the full length of the door or cabinet face.
Why Should You Use a Cremone Bolt?
Apart from the added security, the aesthetic value of a cremone bolt is undeniable. They add a touch of elegance and sophistication to any double door. You can add cremone bolts to your cabinets, too. Additionally, they are quite easy to install, and most DIYers should be able to easily handle the process.

How to Install a Cremone Bolt
So, let's discuss the installation process. First, you'll need to measure the distance between the top and bottom of your doors to determine the length of the rod. It's important to note that cremone bolts come in various lengths, so you'll want to choose the one that matches the height of your doors.
Once you've determined the length of the rod, it's time to drill the holes for the handles and the strike plate. Make sure to use a drill bit that matches the diameter of the handle and strike plate. You'll also need to chisel out a shallow mortise for the strike plate to sit flush with the door frame.
After drilling the necessary holes, insert the rod into the handles and slide it up into the strike plate. Test the mechanism to ensure that it's working correctly. If it's not, you may need to adjust the rod's length or make sure the strike plate is correctly seated and aligned. Voila, c’est tout (that’s all)!
Cremone bolts are an excellent option for DIYers looking to improve the security of their double doors while also adding an element of sophistication. They're relatively easy to install and come in various lengths to match the height of your doors. So, if you're considering adding some extra protection to your double doors, a cremone bolt is worth considering.
