Dimensions (mm)


Standard Supply



The angle framework wraps around the opening, requiring an upstand, lintel and clear wall space to either side. The door leaf is mounted in front of the frame and is larger than the opening (Dimension S).See appropriate door drawing for further detail.
Overall the frame and leaves are larger than the opening due to the ‘wrap around’ nature.


FireLock doors have been tested in accordance with BS 476 Part 22, 1987.
Larger or smaller doors can be made to special order but may not be available with fire rating.
