Barrel bolts are mounted in the inside of a door, allowing extra security while other locks are not in use. They are available in an array of fine finishes.
I have yet to install the latch since removing the prior hardware has proven to be a serious endeavor. I was impressed with the latch and look forward to it's long life once installed.
We recently re screened our porch which included replacing the door. I needed to replace the old barrel lock and was unable to find the right size or finish at either of the box stores. Myknobs came through and I was able to find exactly what I needed. Came fast and works perfectly.
