FLAT WEBBING- Flat webbing is thicker, stronger, and more resistant to abrasion. Flat
webbing is preferred in harsh and abrasive environments, for use in technical rigging,
and in heavy rescue situations. Since the solid flat woven construction incorporates
more nylon, flat webbing weighs slightly more and can be more difficult to handle than
tubular. Type 18 heavy duty flat (needle loom)
webbing is also utilized for technical rescue
rigging applications. It has a rated strength of
26.67 kN (6,000 lbs) and is bulkier than tubular
webbing. The “Type 18” refers to Mil Spec W-

4088K which designates 28 different types of
webbing for military production. 39 40

WEBBING PRODUCTS-
Anchor straps, daisy chains and etriers (sewn
stirrups) are all sewn webbing products used in
rigging applications. Daisy chains are lengths of
webbing constructed with multiple pockets. The
pockets are created by sewing the webbing
against itself with bar tacks or interweaving the Figure 23- Sewn Daisy Chain. Yates
webbing. The standard (Classic) daisy chain Classic Daisy Chain.
produced by Yates Gear is constructed of 11/16 inch
nylon super tape tubular webbing, with an overall rated
strength of 22.2 kN (5000 lbf) and individual pocket
strength of 5.3 kN (1200 lbf) (Figure 23).

OMNI-Sling TM is a nylon daisy chain with woven rigging
pockets manufactured by Rescue Systems, Inc. (Figure
24). This is constructed with 2-inch long slots separated
by 1-inch of solid webbing and creates a tether with an
overall breaking strength of 44 kN (10,000 Ibf). The
breaking strength of the slots is 22 kN (5,000 Ibf). When
this style of sling is under tension the individual pockets
can be difficult to clip with a carabiner.

There are limitations with sewn tethers and it is
