Slam Rail and Ridge Board

Next install the slam rails onto the top of the glass
below the vent aperture (diagram 109). There are 2
grooves in the slam rail, the one nearest the edge
should be used for the aluminium capping and the
one nearer the middle for the cedar capping
(diagram 110).
Drill a pilot hole through the glazing bar, but be
careful to avoid the glass! Then fix with an 80mm
screw through the side of the glazing bar, sink the
head slightly into the timber for a neat finish
(diagram 111).
