CISA Astral S - Euro Double Cylinder 40 - 40 (80mm) Reviews

I really like these Euro cylinders, I've had them for more than 10 years without any issues, in fact the only reason I've ever had to change one is when I lost a key. The lock I removed was perfect after a number of years service. They are easy to install, easy to use and give good hard wearing security. The only improvement I've seen is to include a magnetic element to the key and lock which is maybe something you should think about. Anyway be assured, I will buy this system again for future doors.

We changed all our external locks to one key. These were the lock recommended. They seem excellent quality and were simple to fit. Our local police security adviser complimented us on our choice when he reviewed our security. Expensive but worth it.
