Barton Marine

<h3>Barton Marine: Nearly 80 Years of Marine Engineering Excellence</h3><p>For nearly 80 years Barton Marine has been making world-class sailing blocks, track and cars from our factory in Southeast England. Starting in 1948 in Whitstable, England, famed for its shipwright heritage, our founder Ron Barton, was one of the first to use a fabric based laminated resin called Tufnol and stainless steel to manufacture leisure marine yachting blocks which were much lighter and stronger than previously constructed. This innovative spirit continues to define the brand today, with Barton Marine recognized globally for engineering solutions that deliver reliability in demanding marine environments.</p><h3>Innovation Through Advanced Materials</h3><p>What sets Barton Marine apart is their commitment to material innovation and engineering precision. Throughout their history, they've pioneered the use of advanced composite materials in marine hardware manufacturing. Ron realised that Tufnol was too labour intensive and costly so set about re-designing the entire Barton product range to become the first marine company to use a new plastic injection moulding process using revolutionary fibre glass reinforced plastic materials. This forward-thinking approach to manufacturing has allowed Barton to create products that are simultaneously lighter, stronger, and more corrosion-resistant than traditional metal alternatives.</p><h3>Comprehensive Marine Hardware Solutions</h3><p>Barton Marine's product range spans the full spectrum of marine hardware needs. From their renowned composite winches that offer friction-free operation to their precision-engineered traveller systems, every product reflects decades of refinement. The company manufactures an extensive line of sailing blocks with ball bearing sheave construction, rope clutches, deck organizers, and T-track accessories. Barton, to this day, still continues to manufacture the widest range of T Track accessories in the world. Their electrical components, including <a href="/11485-barton-marine-winch-wiring-harness-19247">winch wiring harnesses</a>, are designed to meet the rigorous demands of marine electrical systems where reliability is non-negotiable.</p><h3>Quality That Professionals Trust</h3><p>As a marine company of many firsts and moving into new and dynamic manufacturing processes Barton Marine has become a global leader in high-quality, well-engineered, modern sailing hardware and accessories. Professional sailors and boating enthusiasts alike have come to trust Barton equipment for its durability and consistent performance. Barton today supplies 35 distributors in 32 countries. This global reach reflects the brand's reputation for manufacturing products that withstand harsh saltwater environments, UV exposure, and the mechanical stresses of marine applications.</p><h3>Engineering for Real-World Reliability</h3><p>Every Barton Marine product undergoes rigorous testing before reaching the market. All tooling work is undertaken in house and extensive testing carried out before release into the market. This attention to detail ensures that whether you're outfitting a racing yacht or maintaining a cruising vessel, Barton hardware delivers the performance and longevity that marine applications demand. Their composite winches, for example, feature virtually self-lubricating mechanisms and corrosion-resistant materials that require minimal maintenance even after years of saltwater exposure. For boat owners working with electrical systems, properly engineered <a href="/11485-barton-marine-winch-wiring-harness-19247">winch wiring harnesses</a> provide the weather-sealed connections and marine-grade wire specifications necessary for safe, reliable operation in wet environments.</p>

Product Details

The Barton Marine Size 7 Single Plain Bearing Stand-Up Block is a high-performance cruising block designed for larger sailing yachts where reliability and strength are paramount. This rugged block features a precision-molded acetal sheave running on a large diameter brass bearing, ensuring smooth, free-running operation even under maximum loads.

Key Features:

  • Precision molded acetal sheave with large diameter brass bearing for reliable performance
  • High-quality injection molded side plates with through-bolted and riveted construction
  • All load-carrying components manufactured from 316-grade stainless steel for corrosion resistance
  • Stand-up block design ideal for use on larger cruising and racing yachts
  • Safe working load of 2,750 lbs (1,250 kg) with break load of 5,500 lbs (2,500 kg)

Specifications:

  • Overall Length: 6-3/8 inches (162 mm)
  • Sheave Size: 2-3/4 inches x 3/4 inch (70 mm x 20 mm)
  • Maximum Rope Diameter: 9/16 inch (14 mm)
  • Weight: 444 grams
  • Safe Working Load (SWL): 2,750 lbs (1,250 kg)
  • Break Load: 5,500 lbs (2,500 kg)

Important Note: Stated break and safe working loads assume all sheaves are evenly loaded, as in a purchase tackle. Uneven loading or loading of a single sheave in a multi-sheave block will reduce the rated strength.
