ABS cylinders are available in 5mm increments per side. When measured correctly the two sizes added together should result in the total overall length of your cylinder e.g. 35mm internal + 45mm external = 80mm overall length. NEVER MEASURE TO THE BLACK CAM - Measure to the centre of the fixing hole to the ends of your cylinder. If you are not confident measuring, please ask for help from your door supplier.

To order ABS Master Thumbturn cylinders simply enter the cylinder size  of the cylinder/s you require. The lock quantity can increased in your basket. 3 keys are included with each lock, additional keys and colour ID key inserts can be ordered with your order or later by key code.
