WARNING:
Some DEWALT SRL's come equipped with a carrying handle. This handle is intended only for manual
transportation and not intended for anchoring the SRL to the structure. Always use the anchorage connector to
attach the SRL to a 5,000 lb. (23kN) structural member.

21) INSTALLATION OF SRL ON
OVERHEAD ANCHOR POINT
As a stationary device, the SRL has to be mounted
on an approved fixed anchorage point which
ideally located at or above the dorsal D-ring of the
user. Connect the swivel eye of the SRL with a self-
locking carabiner to the anchorage. Connect the
snap hook at the end of the lifeline to the Dorsal
attachment D-ring of the Full body harness. The
SRL would extend as the user moves away from the
anchor point, and retracts as the user moves back
towards the anchor point.
If the anchorage is mobile, over a steel cable
or a fixed rail, then the swivel eye of the SRL is
connected to the anchor point with the help of a
self - locking carabiner. The snap hook at the end of
the SRL is connected to the dorsal D-ring of the Full
body harness of the user. Here, since the anchor
moves along with the user, the SRL travels along
with the anchor from one point to the other.
22) TAGLINE
A tag line is a separate line that is used exclusively
for allowing the SRL's line to retract back into the
housing during non-use. The tag line is attached
to the SRL's connecting hook and is long enough
to allow the SRL line to retract fully.
It is recommended that a tag line should be used
to let the line on a SRL to fully retract back into the
housing during extended periods (any time span
that is greater than 24 hours) of non-use. When
an extended lifeline line is left out for extended
periods of time, it may weaken the SRL's retraction
spring quite prematurely hence affecting the
operation of the SRL. These taglines are made of
nylon string, connected to a simple snap hook at
one end.
Many DEWALT SRL's are provided with taglines
of appropriate length. When disconnecting the
self-locking snap hook of the SRL from the dorsal
D-ring of the full body harness, and while the SRL
casing is anchored at a height, then use the tagline
to retract the extended line back to the casing.

•
Connect the tagline snap hook to the snap
hook of the SRL at its eye.
•
Now slowly release the taught extended
lifeline while guiding it with the nylon
tagline.
•
When the entire lifeline of the SRL is retracted
into its casing, then hold the tagline in place
by tying it securely around a post.
•
When you have to pull down the lifeline, just
untie the tagline, and pull it down to bring
down the lifeline along with it.
•
Always use the tagline to retract the lifeline
or to extend it slowly.
•
Always fold the tagline and keep it in a secure
area when not in use.
23) USE OF SRL'S ON LEADING EDGES
Class 1 Self Retractable Lifeline are designed only
to be mounted at or above the users dorsal D-ring.
Class 2 SRL's are specially designed to absorb the
extra energy associated with foot-level tie off. Class
2 SRL's have robust lifelines that prevent breaking
when impacting a leading edge.
Examples of leading edges:
Structural steel I-Beams and purlins.
Steel deck and metal roofing
The DEWALT Class 2 SRL's are engineered such that
in the event of a fall from the edge of a roof or a
terrace, if subjected to contact with a sharp edge,
the lifeline remains intact, while arresting the fall
immediately. This range of SRL's are suitable for
use on edges having radii not greater than 0.005
inch (0.127 mm). For this range of SRL's the position
of the anchorage point can be at the foot level or
above.
NOTE : Class 2 SRLs Can be anchored at foot level
but NOT below foot level. Class 2 SRLs should be
anchored at minimum setback distance of 2ft (0.61
m) from the potential leading edge.
