SCHLAGE61-073 622 (400) B60 Thick Door Kit 2.25 To 4 In

I didn't use this on a thick door, but I repurposed the tail piece for my application. I had a double cylinder dead bolt and wanted to use Simplisafe's smart door lock. Well that is only compatible with single cylinder dead bolts. The problem being was my tail piece was way too short coming from the double cylinder. I didn't want to re-key my deadbolts so I swapped the smaller tail piece with this longer one. I did have to dremel cut it down to the correct size needed, but it's functioning perfect on my door. $13 was well worth it for an easy swap.

I used the kit on a Schlage smart lock, and it worked perfectly. Based on my review of several Schlage smart locks, it appears that the construction of Schlage (smart) locks are the same, and as such, the kit will likely work with whichever lock you purchase.The kit is very long and will work, even if the entire body of the lock is protruding out of the door structure. You will likely need to cut the kit down on one of the marked areas.

I built a soundproof room and door for my home theater and the door is 5" thick. I could not find a way to get the door to pull securely closed to seal because all of the doorknobs and deadbolts are not made for a door of that thickness. I wanted a digital deadbolt to keep the little ones out, but easy access for the adults. I saw this and bought this product along with the deadbolt just to see if I could combine the two and make it work. I was able to weld the two shafts from the kit and the deadbolt into one that would work in the deadbolt, but also be long enough to cover the door's thickness. Fortunately the screws were long enough as they are made to trim down to fit. The door lock works perfect. Now the room is secure and because the deadbolt allows the door to fully seal the soundproofing works so much better. I am positive this will work with other locks than it states if you are willing and able to make modifications to the pieces.

This did the job on my extra thick shed doors. The bolts come with reliefs in them or steps if you will, allowing you to customize the depth. I was able to leave them without modifying or cutting them down. My door around 3.75” thick. The longer lever is easy to install on the deadbolt. Very happy with the outcome.
