USING TUFLEX ® ROUNDSLINGS
Protect Sling from Damage
Sling Hardware and Connections
ALWAYS protect roundslings from being cut or
damaged by corners, edges and protrusions using
protection su昀케cient for each application.
Connection surfaces must be smooth to avoid abrading
or cutting slings. Roundslings can be damaged or
weakened by excessive compression between the
sling and the connection points. Select and use
proper connection hardware that conforms to the size
requirements listed for choker, vertical, or basket hitches
in the charts below.
Do not ignore warning signs of misuse. Cut marks
detected during any sling inspection serve as
a clear indication that cut protection is needed.
Refer to Sling Protection section of this catalog.
Exposure of Slings to Edges
Edges do not need to be sharp to cause failure of
the sling. The following table shows the minimum
allowable edge radii suitable for contact with
unprotected roundslings. Chamfering or cutting
o昀昀 edges is not an acceptable substitute for fully
rounding the edges to the minimum radius. Slings
can also be damaged from contact with edges or
burrs at the sling connection.

WARNING
Exposure of
roundslings to edges
with a radius that is
too small can cause
sling failure and loss
of load.
Measure the edge
radius. The radius is
equal to the distance
between points A and B.

* For further information on minimum edge radius, contact
Lift-All or see WSTDA-RS-1.
Contact Lift-All (or see WSTDA-RS-1), for information
about how to calculate whether a smaller connection
size is allowable when tension on a roundsling is less
than its capacity.
