Let assemble very well!

have ordered this additional lock for an apartment entrance door. These were a DIN door made of wood, middle layer tubular chipboard with aluminum inlay. Since I have otherwise done a lot for work with doors, it was not me particularly difficult to assemble the lock. Previously looked at rest the instructions, checked if everything was okay as far as I'm still the backset of 60mm to 72mm converted. Whether this is necessary, you can check the easiest in which one measures the distance to the existing door lock cylinder from the middle to lock the front edge. Generally one can say that when the lock on the folding edge (ie the wider side of the door) comes, you generally should adjust 72mm. I have the hole with the diameter 35mm with a Forstner bit from two sides drilled so emigrating nothing on the other side. But you can be stretched a piece of board out and then drill from the other side.
The screws that were there all the extent fit, I had to cut anything until the driver pin, but that was previously clear.
Zusäztlich I still glued to heavy duty anchors with injection of cement in order to achieve maximum stability. Overall, I've suburb about 90 minutes needed until everything was ready. I can only recommend the castle.
