- Using one section
of the "Thru-Bolt" casting, insert the stainless
steel bolts into the special recesses located on the side
and weld over the heads.
- Position the
required number of tubes, then slide the second half of
the casting onto the installed bolts.
- Use the special
deep socket to tighten the stainless nut provided until
both halves of the casting have properly aligned the tubes.
- Weld the nuts,
thru pins, and ends, if possible, to complete installation.
