How To Choose The Bowler Hat

The first thing you have to know is that there are three types of combines for domestic locks, which are the European (they are pear-shaped and are the most common), the round and the oval (very rare). Before starting to buy the cylinder you have to measure the thickness of the door, at the same time that you have to observe the distance from the center of the cylinder to the ends, which will allow you to know if it is a centered or off-center cylinder. .

A fundamental rule: the cylinder must not protrude from the outside more than 2 mm. It must be compatible in all its measurements and shapes with the lock (thickness, type, length, slot, shape, among others) so that it fits the door correctly.

Ideally, you should be able to opt for high-security bowlers that have the most up-to-date theft protection systems: anti-copy, anti-bumping, anti-pinch and anti-pick. They are very easy to find, both in neighborhood hardware stores and in large supermarkets that have a DIY section, and their prices are not prohibitive since we are talking about the security of your home.

How To Change The Cylinder Step By Step

We tell you what are the steps to remove the cylinder and install the new one:

To know if you can change the cylinder, you have to check if there is a screw under the pin in the lock. If so, you have to use the screwdriver to remove it.

Insert the key and turn less than 30º to the left and right, you will see how the bowler comes out. In the event that this is not the case, you have to loosen the handle and turn the key again. If it still does not come out, remove the handle (it is only to continue unscrewing and its subsequent installation is just as simple) as it may be this one that is interrupting its output. Then make the turn with the key again so that the bowler comes out.

After removing the cylinder, it is time to install the new one in the lock. Now is the time to screw them with the screwdriver so that it is fixed.

Turn the key to the new cylinder and it is fully installed.
