Product Detail

Our Certus range of cylinders are good quality and include 3-keys per cylinder as standard. We stock many different sizes and finishes for quick delivery. Tested to BS EN 1303

Some terminology explained:

KTD = Keyed to differ – each cylinder has its own 3 unique keys, these keys will not operate other cylinders
CKA13 = Keyed Alike – each cylinder has its own keys, but all keys are the same. So, all keys will operate all cylinders under CKA13 group. This applies across all finishes in the CKA13 group of the Certus range.
UMK C7 = Under Master Key System 7 – each cylinder comes with 3no differ keys unique to that cylinder. When you purchase the C7 master key, this key will operate all UMK cylinders with reference C7. This applies across all finishes in the Certus C7 master key range.

We offer bespoke cylinder systems with master keying/sub master keying and many other cylinder sizes/brands, so please contact our sales team for bespoke enquiries.
