American Standard flat webbing sling is produced from high quality synthetic fiber(polyester) by advanced weaving technology and equipment in various sewing methods. There are four commen types of webbing sling: simplex, duplex, triplex, quadrex.

Synthetic web slings are manufactured from light or heavy duty material that has been surface "treated" to improve abrasion resistance, seal out moisture, and prevent grit from penetrating the web and causing internal wear. Slings can be fabricated from single or multiple plies, may include accessories such as edgeguard, wear pads or sleeves, and are available in several configurations:

Type 1 : Triangle & Choker (TC) - Hardware on each end produces the most effective choker hitch. Can also be used in vertical and basket hitches.

Type 2 : Triangle & Triangle (TT) - Hardware on each end for use in basket or vertical hitch.

Type 3 : Flat Eye & Eye (EE) - Popular, versatile sling used in vertical, choker & basket hitches. Easy to remove from underneath loads.

Type 4 : Twisted Eye & Eye (EE) - Eyes turned at a right angle to sling body. Forms superior choker hitch & allows better fit on crane hook in basket hitch.

Type 5 : Endless (EN) - Economical & adaptable sling with no fixed wear points. Used in all hitches.
