How to correctly measure your cylinders
Measure from the CENTRE of the cylinder fixing screw to both ends of your cylinder. If either end protrudes 5mm or more from the handle then reduce this size as the cylinders should fit as flush to the handle as possible. When measured correctly, the internal & external sizes added together should result in the total overall length e.g 35mm + 45mm = 80mm total overall length. Please do not assume that all your locks are the same size! - this is seldom the case!
Unlike most other Snap Secure locks on the market Cisa Astral S are non-handed, offering equal resistance to snapping and bump key attack from BOTH sides of your door. Example: a 35/50 is exactly the same as a 50/35.

Very impressed with the Cisa locks. Very smooth operation with reversible key and ability to unlock door from outside when my other half leaves his key in the lock on the inside. Recommended
