How do I know which door closer to choose for a fire door?

In the interest of knowledge sharing, we like to share the questions we are often asked so that everyone can benefit from the ‘know how’ that we share on a daily basis. We were recently asked "How do I know which door closer to choose for a fire door?" 

In this short video, Rutland's Lyle McCreadie takes us through the different door closers available and how they work. We take a look at some typical applications where the various door closers may be installed, the types of doors they would be fitted to, and the legislation that outlines the requirements for safe door closer installation on fire doors.
