There are many different kinds of lock cylinder in the market, such as American cylinder, oval cylinder, Chin GB cylinder and Euro standard lock cylinder, it’s for different market, and the cylinder type, size and standard are different.
Euro profile lock cylinder mainly used in Europe at the early stage, it is used with the euro mortise lock together, cylinder size based on DIN18252, section size 17X33X10mm, cam size R15X6.5mm. If the size too big, it will be stuck when operate the lock; if the size too small, it will be sliding when operate the lock.
The Euro profile lock cylinder should compliance with BS EN 1303 standard, durability test 50,000 cycles at least. And fire-rated cylinder needed accordingly for the fire-rated doors.
We have to choose different lock cylinder for different doors and using conditions.
Cylinder with one side knob and one side key, open or lock the door by operating the key from the outside, or turning the knob from the inside. Generally used for interior door and fire-rated door, it’s the most common cylinder type in the market.
Double side key cylinder, we can use the key to open or lock the door from the both side.It’s mainly used for high security doors, such as the entrance door.
Bathroom cylinder is the cylinder one side with knob and the other side with slot, you can open the door by turning the knob from the inside, or rotate the slot by a screwdriver from the out side, it’s used for bathroom doors.
Half cylinder, one side with key, can only open by key from the outside, generally used for the repair and maintenance doors or storage room doors.
Cylinder length= door thickness + escutcheon thickness *2 (generally, there are 2 pcs escutcheon, inside and outside of door). If the mortise lock is not at the middle of the door leaf, you should measure the size and choose the unequal cylinder.
Otherwise, for rebated door, we use unequal knob cylinder generally, we have to confirm the cylinder size on the key side and knob side separately.
There is no right or wrong answer when it comes to Normal Yale key VS Computer key. This is simply a difference in usage habits.
Generally, a cylinder with 3 YALE key or with 5 computer key.
For YALE key, it’s easy to make a copy, security level is not very high.
For computer key, you can open the cylinder by using the both side of the key, it’s more convenient, the computer key is difficult to duplicate, the security level is higher.
There are 5,6 or 7 pins in the cylinder according to the cylinder length, the combination of the pins determine the cylinder mutual opening rate. For example, 6 pins cylinder mutual opening rate is around 1/1800.
We can make the aliked key cylinder and GMK system cylinder by different key combination.
GMK called general master key, the key can only open the own cylinder, the MK1 can open all the cylinder in this MK1 group, the GMK can open all the cylinder group (MK1,MK2…).
GMK usually used in hotel, hospital, school, factory. It’s easier for different door management.
Check the backset of the mortise lock to choose the cylinder fixing screw length. The cylinder fixing screws length= mortise lock backset +10mm
The fixing screws size is M5 screws, the thread of the screw must match the thread of the lock cylinder .
Generally, the material of the lock cylinder fixing screws is stainless 304, stainless 201 or steel plated.
