Build your own crossbar - this must be observed!

An additional door bolt increases the security against burglary, because it is no longer so easy to pry open a door. Corresponding kits are available from specialist retailers and are relatively easy to assemble yourself - that saves costs. The cross bolt for the front door is also called a double bolt lock because two bolts slide from the inside to the outside that secure the door leaf. Read here how to install the additional lock.

Requirements for the installation of a cross ledger

If you want to install a crossbar yourself, you first need a front door with a door leaf that is as flat as possible: cassette compartments and profiles on the surface interfere with the assembly.

Your door leaf should be at least 3.5 cm and no more than 5.0 cm thick so that the basic assembly kit of the cross bar fits. If your door is thicker, it is best to inquire about the corresponding extension parts and extended lock cylinders.

Most prefabricated cross bolt locks are variable in width, but it may be necessary to purchase a special length for particularly wide doors. You should also pay attention to this when purchasing your kit.

How and where do you mount a cross bolt lock?

The crossbar is attached to the inside of a door and extends across the entire width of the door. In the horizontal lock case there are two bolts that extend when the key is turned and engage in the lock cases on the left and right.

Use heavy-duty dowels to mount the lock boxes so that they cannot be torn out of the wall. Sometimes there is not enough space for such a device, then you can chisel out a wall pocket for locking.

The bolt is ideally combined with the lock cylinder of the door so that both door locks can be operated at the same time. You lock the door - the bolts come out. You unlock the door - the bolts snap back.
