There are four primary design configurations
of RSLs in use today.
1. A single side RSL where the lanyard is attached to only one
main riser, usually the left side. [Figure 2-47] Only the one
side is required to release to activate the system. This is
the most common design in use today due to its simplicity

configuration.
2. A dual side RSL where both main risers are
connected with a cross connector which is in turn connected
to the RSL lanyard. [Figure 2-48] Both risers need to be released
for the system to function.
Figure 2-48. Dual side RSL configuration.
The LOR system developed by the French. This incorporates two
lanyards, one from each riser, that are attached to individual
curved pins that secure the reserve container with a dual locking
loop. [Figure 2-49] Both risers must be released for the system
to function.

4. The Collins Lanyard/Skyhook™ system.
This design utilizes a special lanyard which is attached to
the bridle of the reserve free bag. [Figure 2-50] Cutting away
results in the free bag being pulled directly out of the container
by the main risers and results in very little altitude loss.

Since the early 1990s, most (if not all) manufacturers
provide an RSL installation on their equipment either as standard
or optional. If the rigger has a system without an RSL and the
owner wishes to have one installed, the rigger should check
with the manufacturer as to the availability of a retrofit kit
or return it to the manufacturer for installation. Because the
installation of an RSL is an alteration.
alteration to the original design, the rigger
needs approval either from the manufacturer or the FAA. Because
of the nature of the RSL system, it is imperative that the rigger
thoroughly understands the individual concepts. Unless he/she
understands this, and has the required manufacturer’s
instructions, the rigger should not attempt to assemble and
pack a system with an RSL installation. The following describes
the basic design and function of a single side RSL installation
on a one-pin reserve container
