SECTION 4
This step allows glazing to run through when there is not
a bar at the finial point.
With all other necessary preps complete, offer up the
Weathering Shield into position. Using a straight edge
(as shown), project and mark a line (‘A’) using the glazing
‘V’ groove (indicated inset) parallel with the centre of the
bar closest to the finial point.
Mark line ‘B’ – this should intersect line ‘A’ and line through
with the ‘upper edge of block (25mm glazing) or ’35mm
dashed line’ (35mm glazing) – see below.
Mark line ‘C’ – this should intersect line ‘A’ and the virtual
‘MIDPOINT’ – see below.
Remove segment and repeat on opposite side.
