Multi-point patio locks are something lots of people want or need. These locks are a little more complex than your regular front door lock set. The multi-point mechanism have 3 different points where a bolt will come out of the door to lock inside part of the door jamb - the top, bottom, and the side of the door just like any basic door lock. The reason these locks are a must have is mainly for the security factor. It's three locking bolts compared to one. These are also purchased for the style as well has how well the function (for more info on multi-point locks check this post).
Marvin Integrity provides doors with the multi point mechanism and some door hardware. We give you the option of more styles for your Marvin Integrity doors. So, if you are wanting to replace your old hardware for something new, you will want to check Emtek's "configuration 1" on this page, or look at the image below.
You will want to make sure the measurements of your existing mechanism match up with this configuration before you order. After you have found that it does match, check out all the different designs from Emtek you can choose from, under Emtek 3 Point Lock Trim Configuration 1. There are many many options, and the best way to start is by first picking the plate you like and then going to the page, because there are even more levers to choose from that will go with that plate (check under description box on the page of the plate you chose).
*Please note that we do not carry replacements for the Marvin Integrity interior locking mechanism. The Emtek multi point hardware includes only the handle and plate (for interior and exterior of the door), and keyed cylinders (where applicable) that are mounted to the door and attached to existing mechanism. The mechanism is installed with your Marvin Integrity door, which is probably a great thing because I'm not sure how easy that would be to install.
