Searching for Miliani Brothers sunroom storm door
Thanks for reaching out to us! We did carry this handle set at one time, but due to a high number of customer complaints concerning its quality, we stopped selling it. These broke often and early and didn't live up to SWISCO.com standards.
You will be better off contacting a local locksmith and having them adapt a prime door lockset to your sunroom door. It will work way better than the original and will save you more money in the long run, too, since you won't have to replace it every couple of months.
Can you recommend a door knob/deadbolt set that could be easily modified to work on this door? The only solution I have been offered is to have the entire room removed and replaced.
Our experts have done some research and have found the best solution would be to purchase a prime door handle and have it altered by a locksmith to fit a sunroom door. Unfortunately, we do not have a record of a specific locksmith in your area that would be willing to make the necessary modifications. We recognize that this is not a straightforward solution and we are still looking into finding a more direct replacement.
