6) Tighten rear diagonals so harness is secure
against student’s back. Ensure elastic keeper is
pulled up to secure loose webbing.
7) Tighten horizontal back strap. The lower harness
should now be fitted and snug. Ensure elastic keeper
is pulled over to secure loose webbing.
NOTE!
As of December 31st, 2007, all Strong Tandem Student
Harnesses are required to have the Y-Mod webbing
modification that connects the back pad and leg straps
together. (If you encounter a Student Harness in the
field without a Y-Mod, contact Strong Enterprises
before the next jump. Y-Mod field modification kits are
available and Strong Enterprises also can perform the
modification.)
8) Tighten Y-mod strap located below harness back
pad. The Y-mod does not need to be excessively tight
to work correctly. Ensure student can still lift their
legs with Y-mod secured, if the Y-mod is restricting
the student from lifting their legs, loosen the
adjustment to allow movement.
