Industrial Splicing & Sling

What Industrial Splicing & Sling does

Industrial Splicing & Sling, LLC is a family-owned industrial rigging equipment fabricator and distributor founded in 1940 in Tulsa, Oklahoma, and currently operated by the father-son team of Larry and Scott Postelwait. The company sells a broad rigging product portfolio including wire rope, wire rope slings, chain slings, synthetic slings, cargo control, rigging hardware, fall protection, lifting beams, and permanent lifting magnets, with in-house custom sling fabrication across wire rope, web, and chain configurations. It complements this product line with paid and free professional services: rigging inspection and repair, certified proof and load testing using 50,000 to 150,000 lb hydraulic test machines calibrated to ASTM E4 and ISO 7500-1, ASME B30.20-compliant permanent magnet breakaway testing, and free on-site OSHA/ASME safety training.

The company serves five named verticals — Construction, Oil & Gas, Manufacturing, Aerospace, and Transportation & Logistics — with Oil & Gas as the historic anchor and Construction and Manufacturing as primary growth areas. Distribution runs through three physical stores in Tulsa, OK (headquarters), Little Rock, AR, and Fort Smith, AR, supported by same-day in-store pickup, local delivery in the Tulsa and Fort Smith metros, nationwide UPS/FedEx shipping, and phone/email inside-sales with quote-based pricing on all non-stocked custom work. The company is a member of the Associated Wire Rope Fabricators (AWRF) and the Web Sling and Tie Down Association (WSTDA), and positions OSHA/ASME compliance and certified testing as its core commercial differentiators.

The business is privately held by the Postelwait family with no disclosed institutional investors, parent entity, or subsidiaries. No revenue, headcount, or financial data has been disclosed in available source material, so scale inferences are necessarily directional. Marketing is primarily conducted through the company website, organic LinkedIn and Facebook pages, and industry association channels.

Emerging players

• Lift-All: U.S. manufacturer specializing in synthetic web slings and round slings, the same product categories that ISS fabricates in-house; a more focused competitor on the synthetic sling side of ISS's product line.
• Liftex: Manufacturer of synthetic and wire rope slings, sling protection, and related rigging products — a focused competitor on the sling manufacturing side of ISS's custom fabrication business.

Broad incumbents

• The Crosby Group: Largest U.S. manufacturer of rigging hardware (shackles, hooks, blocks) sold through distributors like ISS; a broad incumbent that supplies much of the category and competes indirectly via the supply side rather than direct sales.
• SpanSet / Gunnebo Industries: Global manufacturer of lifting and load-securing products including slings, tie-downs, and fall protection — a broader incumbent with overlapping product lines but a wider geographic and category footprint than ISS.

Direct peers

• Mazzella Companies: One of the largest U.S. distributors of overhead cranes, rigging, and lifting solutions with in-house fabrication, on-site inspection, and safety training — the closest direct comparable in scale, service model, and vertical mix to Industrial Splicing & Sling.
• Hercules SLR: Canada-based rigging, lifting, and safety services provider with branch locations offering inspection, testing, and training — closely comparable in product breadth, service model, and customer verticals.
• Continental Western (ConWest Safety): U.S. distributor of rigging, cargo control, and fall protection products with fabrication, testing, and training services — a comparable full-line rigging supplier competing for the same industrial buyers.
• Bishop Lifting Products: Multi-branch U.S. rigging and lifting distributor that fabricates slings, performs proof load testing, and offers rigging inspection services — directly overlapping with ISS's core product, service, and go-to-market model.
• Allied Rigging: Multi-location rigging distributor serving industrial and construction customers with slings, hardware, and on-site inspection services — overlapping with ISS in product, service, and customer base.
• Certex USA: Rigging and lifting products distributor with branch locations across the U.S. that sells wire rope, chain, and synthetic slings alongside inspection and testing services — a comparable regional-to-national distribution model.
