Four Generations
of American Craftsmanship
For over 50 years, OSP Sling has built a reputation for dependable, American-made lifting products trusted by industries across the country.
Sequim, Washington.
Family-Owned & Operated
Established 1974
OSP Sling Products began more than half a century ago with a simple idea — build lifting slings that people can trust their livelihoods to.
From a small family operation to a full-scale U.S. manufacturer, we’ve grown through four generations of leadership that share one core value: quality above all else.
Every sling we make reflects decades of refinement, industry experience, and an unwavering commitment to safety. Today, our products are used by construction crews, manufacturers, transportation companies, and rigging professionals who know that dependable gear keeps people safe and jobs moving.
Quality isn’t a department here. it’s a mindset.
We source 100 % domestic nylon and polyester, partner with trusted U.S. suppliers such as Carolina Webbing and Filtec Precise, and handle every stage of production in-house at our Sequim, Washington facility.
Our 600,000-lb ASTME-4 certified Proof-Cert testing machine allows us to verify every product’s performance before it leaves our doors, ensuring that the gear you depend on performs exactly as expected — every time.
Our Commitment
to Quality
Grounded in Family,
Driven by Integrity
OSP Sling remains a family-owned business under the leadership of Todd M. Negus, President, representing the fourth generation of a company built on trust, craftsmanship, and service.
We believe our relationships - with customers, vendors, and our team - are as important as the products we build.
That’s why customer service continues to be the foundation of everything we do.
“We take great pride in the quality of our entire product line. Quality isn’t just something we measure — it’s something we live by.”
