To join twist lock pipes together, simply align the beads
of the male end with the grooves of the female end,
twisting the pipe until the flange on the female end
contacts external flange on the male end. It is recom-
mended that you secure the joints with three (3) sheet
metal screws, however, this is not mandatory with twist
lock pipe. (Fig. 17)
To make it easier to assembly the joints, we suggest
putting a lubricant (Vaseline or similar) on the male end
of the twist lock pipe prior to assembly.
