Reinforced boxes are used for transoms from 1.6 m to 4.5 m wide. However, these can be less than 1.6 m wide.
These boxes are reinforced with 3 mm galvanised steel brackets. The brackets are positioned in the box at intervals of 1.2 m and hold the profile in place.
Fixolite reinforced boxes are made of graphite polystyrene (grey).
All FIXOLITE safes have undergone extensive testing and are certified by an independent body.
