Description

Delivery may take up to 7 working days on this product depending on size ordered and if extra keys need to be cut. If you require further information on delivery timescales please contact us. Locks built to code do not come with any keys.

It has been proven that a burglar can gain entry to your property in as little as 13 seconds.

To combat this Avocet has created the 3 Star, British Kitemarked, anti-snap ABS euro cylinder. 

ABS is a retrofit product which means you can simply remove your old lock and replace it with ABS

  • Not supplied with keys - lock only
  • Measurements are taken to the centre screw on this lock
  • Snap Secure Technology - Cam locks against the internal locked side of the cylinder making the cylinder impervious to manual attack after snapping
  • ANTI-SNAP, ANTI-DRILL, ANTI-PICK, ANTI-DRILL
  • TS007 3 star rating
  • Insurance recommended British Kitemark™ stamp
  • Master Locksmith Association's Sold Secure Diamond standard

Please Note: 30mm cylinders do not display a kitemark due to reduced numbers of key combinations. 30mm cylinders do still snap off at the sacrificial point in front of the cam , this ensures an intruder cannot gain access into the lock case.

Not sure which size cylinder you need?

Euro cylinders are measured in two halves, separated by the central fixing screw. Take both measurements from your existing cylinder before ordering, and match them to the size listed above.

A — Internal side
Measure from the centre of the fixing screw to the outer edge of the cylinder on the side that faces inside your home. Common sizes are 30mm, 35mm, 40mm, 45mm, or 50mm.

B — External side
Measure from the centre of the fixing screw to the outer edge of the cylinder on the side that faces outside your home. Common sizes are 30mm, 35mm, 40mm, or 45mm.

Cylinders are typically described as A/B — for example, a 35/45 cylinder has 35mm on the internal side and 45mm on the external side. Get both measurements right and the cylinder will fit your door perfectly.

Still unsure? Send a photo of your existing cylinder to info@homesecureshop.co.uk and we'll match it for you — or call 0151 521 8089 to speak to our team.
