TCP Base Section Assembly with Flat Floor

Note: Failure to completely compress the gasketing may result in air leakage.

1. Join the two units and secure with factory-provided 5/8-inch flat washers and 5/8-inch X 2-1/2-

inch grade 9 bolts though each of the six holes. See Figure 10.

2. Caulk the overlapping flange along the length of each split to maintain a seal.

Note: Use a polyurethane or equivalent caulk.

3. Before installing the pre-cut 4-inch 18-gauge joining strips, pre-drill holes in the floor using the

4-inch strip as a guide with a 7/32-inch drill bit at 12-inch centers.

4. After holes are pre-drilled, apply an ample bead of caulk to the joint then install 4-inch strip with

#14 sheet metal screws uniformly straddling the split.

5. In cases of tread plate floor, some job specifications may call for the seam to be welded. In those

cases make sure the sections are pulled together tightly then weld with appropriate method.

The floor construction in those cases will be such that the heat from welding will not affect the

insulation.
