NOTES
A1xA2 - Length and width of the opening
Length can be selected independently of the width, from the minimum dimensions shown in the tables up to a maximum of 200x100 (A1xA2) with 5 cm intervals. Frames are built 2 cm shorter and narrower than the opening.
B - Frame height
Frames can be made with a minimum height of 16 cm (20 cm for Ligna 3) up to any height requested. For flat roof access, the minimum height of the frame is 50 cm. In this case, the customer must specify the total thickness of the ceiling (including the roof finish) to which 15 cm must be added to provide the necessary clearance for trap door rotation.
C - Room height
Stairs are made to the specified measurements and can also be adapted to accomodate differences in height of up to 5 cm.
E - extension clearance (distance from obstacles)
Inform the manufacture of the position of any obstacles that may prevent full extension of the stair, so that the stair foot rest point can be adjusted accordingly.
F - Stair foot rest point
The values given in the tables are guideline and in no way binding.
