INSTALLING WEATHER STRIPPING ON BOTTOM EDGE OF CBC

Once all Rivnuts have been installed, the CBC can be lifted from its shipping pallet and lowered onto a

set of supporting blocks (1) placed between the pallet and the CBC. The blocks are used in order to raise

the CBC up off the shipping pallet. This will permit access to the bottom edge of the CBC that contacts

the vehicle bed. Two thicknesses of weatherstripping, 3/16 and 1/8 inch are supplied in 50 foot rolls and

are included in the mounting kit.

Install the first layer of weather stripping (3/16 inch thick x 1 inch wide) (2) along the bottom edge (3) of

the CBC by removing the protective paper (4) backing and pressing the adhesive side (5) of the weather

stripping in place on the CBC. Weather stripping is NOT applied to the carrier mounting angles (6), it is

applied to the bottom edge (3) of the CBC itself and the underside of the threshhold opposite the bottom

edge.

Once the first layer (2) of weather stripping is in place, place an additional layer or layers (as required) of

weather stripping (1/8 or 3/16 inch thick x 1 inch wide) (7) in those areas identified earlier where gaps

greater than 1/4 inch were observed between the CBC and the vehicle bed. Then add a second complete

layer of weatherstripping (1/8 inch thick x 1 inch wide) (8) over the first layer (3/16 inch thick x 1 inch

wide) (2) and over any additional layers (7) that were added to compensate for gaps.

Once a minimum of 5/16 inch of weather stripping has been installed on the areas of the of the CBC not

obscured by the supporting blocks (1), lift the CBC slightly with the hoisting sling, move the supporting

blocks (1) to an area where weather stripping has already been installed, and install weatherstripping on

the remaining non-weather stripped areas of the CBC as detailed above.

Once all weather stripping has been installed, RTV sealant must applied to the underside of the installed

weather stripping as detailed in the next section.
