The Cableguard TM was heat-sealed using inflatable
heating blankets. The blankets were provided
specifically for the project since they were dependent
on the diameter of the cables. The blankets were
inflated to press the flexible heating elements
uniformly onto the cable surface and then heated to
seal the wrapping (Figure 11).

To promote an air-tight seal, the wrapping was
applied to create a triple overlap. The width of the
triple overlap was set to a minimum and maximum
width to provide a uniform appearance and promote
heat sealing of the overlaps (Figure 10).

Both the Westbound and Eastbound Bridge cables
were entirely unwrapped and rewrapped with the
Cableguard TM wrap system. Following the wrapping,
an anti-skid surface paint and grit was applied to the
top of the cable as part of the finish-work (Figure 12).
