Butt-strap join
By combining packing plates with thicknesses of
2, 3 and 4 mm, closures can be made in a 1 mm
increment-grid.

Important note:
● The screws (D) are only for transferring
the shear force. Owing to the tolerances,
they must be fitted with a play of
a ... min. 5 mm. Secure the connection by
countering with a second nut.
a ... min. 5 mm
● Under load, a gap of up to 5 mm and/or
up to 2% buckling may occur between the
screws and the drilled holes, due to pro-
duction-related tolerances.
These tolerances can be equalised by
installing packing plates.
● Packing plates must be fitted wherever
joins are subjected to bending stress.
