SYNTHETIC SLINGS
Synthetic slings are an essential component in today’s lifting and rigging environments, offering a lightweight, flexible, and highly durable alternative to traditional steel options. At Campbell‑Mack Supply, our selection of synthetic slings is designed to provide exceptional strength while protecting your load and equipment from damage. Manufactured to meet rigorous industry standards, these slings deliver reliable performance across a wide range of applications, including construction, manufacturing, transportation, and maintenance operations.
Known for their ease of handling, synthetic slings reduce operator fatigue and improve overall efficiency on the job site. Their soft, non‑abrasive material is ideal for lifting delicate or finished surfaces, while their reinforced construction ensures dependable load control and long service life. Trust Campbell‑Mack Supply for safe, high‑quality synthetic lifting solutions.
Nylon Web Slings
Physical properties:
-
Nylon will produce a significant stretch, 8%- 12% at capacity making it an excellent shock absorber. Best for live loads including towing.
-
May lose up to 20% capacity when wet, however, in-house testing has revealed our nylon broke beyond published breaking strength even when saturated.
-
Maximum temperature of 99°C, 210°F and low of -70°C and -94°F.
-
Melting point 216°C - 420°F.
-
Fair UV resistance.
-
Good resistance to oil and organic solvents, formaldehyde and alcohols.
-
Not recommended for use with phenols, alkalis, iodine and acids. Chlorine should also be avoided.
-
Nylon is mould and mildew resistant.


Polyester Web Slings
Physical properties:
-
Range of 2% - 4% Elongation at capacity.
-
Loses no strength when wet.
-
Maximum temperature of 90°C, 194°F while lows up to -40°C, -40°F do not affect the strength of the sling.
-
Good UV resistance.
-
Good resistance to most acids and alkalis. Poor resistance to ethers and aldehydes.
Polyester Round Slings
Physical properties:
-
Double jacketed for extra durability and protection.
-
Maximum temperature of 90°C, 194°F while lows up to -40°C, -40°F do not affect the strength of the sling.
-
Good UV resistance.
-
Good resistance to most acids and alkalis. Poor resistance to ethers and aldehydes.
-
Polyester round slings offer a high strength-to-weight ratio and conform to almost any load shape.
-
Each sling is individually proof-tested with certificate.

Web Connectors
Web sling connectors are designed to join synthetic web and round slings to conventional rigging hardware (master links, rings, eye hooks) while maintaining sling efficiency.
Key Features:
-
Wide bearing surface: Increased spool/bow radius distributes load across sling fibres to reduce pinching and wear and help achieve 100% of the sling’s rated WLL when properly used.
-
Alloy construction & traceability: Each fitting includes product identification for material traceability and is proof‑tested per industry practice.
-
Fast assembly: Field assembly to master links or eye hooks—no special tools required.
Typical uses:
Building bridle assemblies, connecting web/round slings to top links or hooks, or joining two synthetic slings.
Compatibility:
Designed for Type III (eye‑and‑eye) web slings and synthetic round slings; check webbing width/frame size against connector size and WLL.
Standards & guidance:
Meets contact width/stock diameter guidance for synthetic slings (WSTDA‑RS1) and follows best practices for fitting selection and rated loads.
Web Sling Shackles
Web sling shackles (e.g., S‑281) connect web/round slings directly to pad eyes, eye bolts, and lifting lugs while protecting the sling at the connection point.
Key Features:
-
Wide‑body bow: Expanded bow with smooth edges provides a larger radius to reduce bunching and fibre damage.
-
Alloy steel & marked pins: Each shackle includes PIC/traceability, stamped WLL, and is designed with a 5:1 design factor.
-
Proper positioning: Keeps web sling centred for consistent loading; tapered eyes may be required for wider webbing.
Typical WLLs & sizes:
Common capacities range from 3‑1/4 t to 8‑1/2 t depending on webbing width/eye size (verify dimensional fit before use).
Use cases:
Attaching web slings to lifting lugs, pad eyes, or eyebolts where a standard anchor shackle or hook would compromise sling efficiency.
Compliance:
Refer to the manufacturer tables for webbing width, eye width, and proof‑load guidance; follow WSTDA‑RS1 and ASME B30.26 practices.
Bolt-type Sling Shackle & Screw-pin Sling Shackles
Select a bolt‑type (safety) shackle for long‑term or dynamic applications and a screw‑pin shackle for quick, temporary rigging.
Bolt‑type (Safety) Shackles:
-
Pin secured by bolt + nut + cotter: Resists pin rotation and loosening under shifting loads; suitable for multi‑leg, side‑loading, and longer‑duration lifts.
-
Best for permanence & overhead work: Common in bridle assemblies and applications where loads may move on the pin.
Screw‑pin Shackles:
-
Fast connect/disconnect: Threaded pin installs quickly for temporary lifts or tie‑downs; not recommended for permanent installations where rotation may occur.
Selection tips:
-
Match WLL to the entire rigging system; check bow size/radius against sling type (web or round).
-
For side loading or multi‑leg connections, use appropriately rated anchor/bow shackles and apply manufacturer's derations.
Web Sling Connecting Links & Sliding Choker Hooks
Combine web sling connecting links (e.g., S‑280 Web Connector) with sliding choker hooks (e.g., S‑287) to build efficient synthetic sling connections and controlled choker setups.
Web Sling Connecting Links (S‑280):
-
Connect web/round slings to master links, rings, or eye hooks; vinyl covers and spools help position and protect sling eyes.
-
Wide spool radius: Improves load distribution on internal fibres and helps maintain sling WLL when used correctly.
Sliding Choker Hooks (S‑287):
-
Reduced friction at the choke point: Hook and spool system minimizes abrasion and fraying during choking.
-
Field‑friendly: Enables quick, repeatable choker hitching on synthetic slings while keeping the sling correctly seated.
Applications:
Sewing master links into a web sling eye, assembling adjustable bridles, or creating low‑abrasion choker hitches for synthetic web/round slings.
Guidance:
Confirm webbing width/frame size against connector/hook dimensions and follow WSTDA‑RS1 and ASME B30.26 recommendations for fittings selection and proof testing.
