Security Cylinders

Security cylinders are a fundamental part of security in any premises. As intruders have become more resourceful and are able to easily access tools to break locks, a high quality cylinder is more important than ever.

At Thornhill Security, we stock a range of high quality security cylinders with enhanced security features including drill protection, key duplication protection and resistance against the most common forms of attack to keep your home or commercial premises safe from intruders.

Our expert team can help you choose the right cylinder based on your lock size and premises type – giving you the highest level of security for your needs and budget.

All of our security cylinders can be sold individually or as part of a master key system.
