What are the door sizes? What is the clear opening?

The sizes listed are external frame sizes.
We offer side panels and over panels if you need to add to the width or height of the door. We also offer a cut down service to reduce the height of the door
To calculate the clear opening (when the door is open), subtract 135mm from the width dimension. E.G. 895mm-135mm=760mm clear opening

What is Security Trim?

The security trim kit fits around the perimeter of the door frame, preventing any packing from being seen externally and making the door as a whole more secure.
It hides un-level or large gaps, hides the position of fixings eliminating the risk of tampering from intruders and crucially protects the fixings from attack.
