61-073 622 (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 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.

Make sure when you buy this that you get the right pin that works for your lock. I advise buying the lock first and viewing the pin that you get and match it up. I didn’t do that and they sent out the wrong one. I’m just gonna modify it and cut the back off and epoxy it into the slot. I’m giving it five stars because it actually fits on one side and the length is right and the bolts that it comes with are also correct. It’s just the wrong pin

The biggest issue with this extender kit is that the end of the "turning pin" is a different shape to the end of the original and it does not fit into the original lock. In the picture, the original is at the top and the replacement is at the bottom. To fix this you need to cut off the end off and then measure the length needed so that the cut off end fits into the groove inside the door lock. The pin and screws are designed to be cut to size to fit the width of the door but even with these cutting guidelines and with the extra cutting to remove the end of the turning pin, the pin was too long so it had to be measured and then cut further to fit. The replacement pin is not compatible and Schlage should just offer various extender kits to fit various door widths to avoid the need to cut to size.

We bought a standard door sized electronic digital lock that didn't fit our door. Ordered this kit and it solved our problem. I would recommend not getting an oversized door to start with (haha), but if you do have one, this product will help!

Good

I had to cut it to fit with multi tool . Finally got it to work . Not sure if I misread or not but was not as u had assumed would work out of box .

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.

This is what I look forEasy to work withVery good

I constructed garage carriage doors that I wanted thick enough to insulate. This kit made it possible to add a deadbolt.
