Detainer

If you're thinking of connecting a burglar alarm to any of your external doors, you will need to fit your door with a detainer mortice lock which has a microswitch. A detainer without a microswitch still offers a higher number of combinations than a 5 lever deadlock and as such, is a more secure choice.

When you have the found the right detainer for your application, you can place your order quickly and easily using our secure online shopping facility.
