The main risers must have an attachment location
for the lanyard. In this example, a small ring is installed
near the lower hardware end of the riser on the inboard side.
[Figure 2-51] It is desirable to locate the ring as close to
the lower end as possible so that the pivot arc of the riser
does not load the lanyard. This allows the riser end of the
lanyard end to be as short as possible. If there is excess lanyard,
it is difficult to stow and it is possible for the lanyard to
become snagged and unseated. It is important that the correct
risers with attachment ring be installed. While many risers
have a ring installation, not all are installed at the correct
location. Consequently, the lanyard length will not match the
factory dimensions. This can result in premature reserve activation
when the main is deployed.

Most RSL lanyard designs have a snap shackle
or similar release device mounted at the riser end of the lanyard.
[Figure 2-52] This allows the user to disconnect the lanyard
under certain circumstances. The most common one involves landing
in high winds where the parachutist may wish to cutaway the
main canopy to prevent being dragged. If the lanyard were not
released, the reserve would be deployed as the main is cutaway.
