How to measure your security handle

ERA Door Security Handle securityIntroduction


To further enhance security and provide a visual deterrent you may also wish to fit a security handle, which completely eliminates the risk of your cylinder being compromised.

Combine with a secure cylinder that clearly shows the BS Kitemark.

A video demonstrating this can be found in the ‘how to’ section of the website.



Step 1 : Door type

Spindle lock security


For different door materials it’s common to need different screw and spindle lengths to accompany the handle (these are normally provided in the pack).


Generally for timber, composite and 60mm PVCu doors the 44mm screws and spindle is used; and for 70mm PVCu doors the 70mm screws and spindle.



Step 2: Measuring



When fitting a security handle please measure out the screw holes as shown in the diagram below:
