You may wonder how to know which is the best cylinder for your home lock. Because not all cylinders work for all locks. Therefore, it is essential that you evaluate several things: material and thickness of your door —metal or wood—, its security level and of course what size and shape has your bowler hat.

The pear-shaped bowler hat is the most common in Europe. Its upper part is wider and rounded, while the lower part is narrower. Most wooden doors have this type of cylinder.

On the other hand, round bowlers have a cylindrical part, while oval bowlers are very rare. As for the bowler material , usually has a nickel-brass or chrome coating. He nickel is the most recommended, due to its great endurance wear and tear over time.

As for the measurement or size of the bowler In addition to the standard one (30x30 mm / 35x35 mm) you can find these models:

Centered cylinders

Taking into account the central part of the bowler, it is divided into two equal parts. Their measurements are usually 30x30mm , 35x35mm or of 40x40mm .

Asymmetrical / off-center bowlers

Unlike the centered bowler, the asymmetric or off-center bowler has two parts that are not symmetrical. It usually measures 30x40mm , 30x50mm o 40x50mm .

Half cylinder cylinders

They measure just half the size of the standard bowler, that is, they are made of 30x10mm . These cylinders are designed for doors with a thickness less than usual. Never forget that the bowler cannot protrude outside the door more than 3 mm . Otherwise, thieves could break into it and rob you.
