FIGURE 2Il-l. Routing BOF tubes in TRB.

a. Snap the BOF tubes into a 7-tube clip or lace the tubes flat to a small plastic or metal bar. Place the longest BOF tube to the rear of the box with each successively shorter tube placed to the front of the previous tube (if the BOF tube lengths are staggered).

b. Route the group of BOF tubes along the side of the box securing the group to the box mounting brackets (if available) using self- clinching straps.

Step 6 - Repeat steps 3, 4 and 5 for each BOF cable entering the tube routing box.

NOTE: The tubes of each successive BOF cable should be shortened approximately 50 mm (2 in) compared to the previous BOF cable routed on the same side of the box.

NOTE: Spacers may be used to separate tube groups to facilitate access.

Step 7 - Observe the tube connection chart or other approved drawing. Identify BOF tubes that will not be connected and end seal them in accordance with Method 2Jl of this standard.

Step 8 - Slide a straight tube coupler or a tee tube coupler onto the tube and firmly seat the tube coupler on the tube.
