APPLYING RTV SILICONE SEALANT, FINAL ASSEMBLY OF GUSSET PLATES

NOTE

Sealant should be applied only if the CBC is to be immediately mounted

to the vehicle bed. The sealant has a working time of approximately 20

minutes and will start to cure after that time. Installing the CBC on the

vehicle after the sealant begins to cure may adversely affect the

sealant's ability to properly bond with the vehicle bed.

Once all gaps have been identified and eliminated as described above, a bead of RTV (silicone) sealant

must be applied where the weather stripping contacts the vehicle bed and around the threshold area.

To apply the RTV sealant, raise the CBC to a comfortable working height using the hoisting sling.

Install the supplied cartridge of sealant into a standard caulking gun. Trim the tip of the cartridge so that a

bead approximately 3/16 to 1/4 inch in width can be applied.

Apply a continuous bead of sealant (1) 3/16 to 1/4 inch in width on the surface of the weather stripping (2)

along the outer edge. Start at one point at the underside of the CBC and move around the entire

perimeter of the CBC applying sealant to all weather stripping surfaces.

Once sealant has been properly applied to all weather stripping surfaces, the CBC should be lowered into

position on the vehicle bed. Take care to return the CBC in the same position so that the hole in the

gusset plates align with the slotted hole in the vertical trailer support and that the flat portion of the gusset

plate contacts the vertical trailer support.

Install one 7 inch bolt (3) and flat washer (8) through both slotted holes (6) in the vertical trailer support

(7). Install a flat washer (8) and locknut (9) on the end of the 7 inch bolt (3). Tighten the hardware on each

gusset plate securely.
