Fitting Requirements
Headroom Requirements:
- 77mm lath doors require a clear 300mm headroom above the opening, and side room up to 90mm.
- 55mm lath doors require 205mm headroom above the opening, and side room up to 70mm.
- On every door there will always be one lath in the opening so whatever size lath you choose you will loose either 55mm or 77mm on the height.
