Polyester Roundslings
Tuflex® versus Sling Webbing
Tuflex

(Side View)
Roundsling construction (as shown above) protects all load carrying core yarns from abrasion with an independent,
woven jacket. Replacement is not necessary until the red or white core yarns can be seen through holes in the
jacket. When core yarns are visible, the sling must be removed from service. Tuflex roundslings provide double-wall
protection for extended sling life.

Braided Tuflex length tolerance is ± (2" + 5% of the ordered length with sling at rest). At its rated capacity, braided
Tuflex will stretch approximately 9%.

The following sling length tolerances apply to roundslings when new, at the time of 昀椀nal manufacture. Standard
Length Tolerance – Endless and Eye & Eye style Roundslings should be made in conformance with the length
tolerance values listed in the table below. Matched Set Length Tolerance – When multiple legs of a bridle sling are
made, or when multiple slings are prescribed to be made within a Matched Set Tolerance, their length variance
from their nominal length shall remain within a dimension equal to one-half of their corresponding Standard Length
Tolerance Values listed in the table below.
