Ronstan

<h3>About Ronstan – A Legacy Built on the Water</h3><p>Few names in the sailing world carry as much weight as Ronstan. <strong>Founded in 1953</strong> by Ron Allat and Stan Lenepveu, the company began as a small boatbuilding operation in Highett, a suburb of Melbourne, Australia. What started as handcrafting custom yacht fittings for fellow sailors at the nearby Black Rock Yacht Club steadily grew into one of the most respected sailboat hardware manufacturers on the planet. The brand name itself is a nod to its founders — Ron and Stan — whose passion for sailing and precision craftsmanship shaped the company's DNA from day one.</p><p>Today, <strong>Ronstan International</strong> is a globally recognised manufacturer and supplier of sailboat hardware, rigging components, winches, sailing gear, and accessories, with its head office remaining in Braeside, Victoria, Australia. The company has established manufacturing facilities in Australia, Denmark, and Indonesia, along with sales offices in the United States, and distributes products to sailors in over 40 countries around the world. In November 2023, Ronstan joined <strong>Groupe Wichard</strong>, aligning with an industry leader whose portfolio spans more than ten world-renowned brands in the sailing and safety markets — a move that further strengthens Ronstan's global reach and product offering.</p><h3>Engineered for Every Sailor, Proven at the Highest Levels</h3><p>Ronstan's reputation spans the full spectrum of sailing — from first-time dinghy sailors to elite competitors at the America's Cup and Olympic Games. The brand serves as the official supplier to the Australian Sailing Team, and Ronstan hardware has appeared aboard medal-winning boats across multiple Olympic campaigns. That pedigree at the pinnacle of racing directly fuels the innovation available to everyday sailors: the demanding performance requirements of top-tier competition have driven many of the technical breakthroughs found throughout Ronstan's broader product range.</p><p>The company's catalog encompasses well over 2,000 products, including pulley blocks, traveller systems, furlers, rope cleats, stainless steel fittings, shackles, snap shackles, and winches. Whether you're outfitting a small racing dinghy, a family cruiser, or an offshore race yacht, Ronstan offers hardware designed and tested to perform in real-world conditions. Their in-house capabilities span design, engineering, precision injection moulding, CNC machining, metal pressing, and assembly — all of which contribute to the consistent quality sailors have come to expect from the brand.</p><h3>Top Ronstan Product Categories</h3><p>Among Ronstan's most popular product lines are their <a href="/11561-ronstan-tiller-extensions-accessories-202641">Tiller Extensions &amp; Accessories</a>, which encompass both their renowned carbon fibre and alloy tiller extension ranges.

The Ronstan Series 30 High Load Exit Box is designed for applications where lines need to be led through decks, bulkheads, or spars with minimal friction and chafing. This single-line exit box features plain bearing sheaves that excel in halyard applications and other scenarios where high static loads are common.

Key Features:

  • 30mm (1-3/16") diameter Nylatron sheave for smooth, low-friction operation
  • Grade 316 stainless steel cheeks for maximum corrosion resistance
  • Accommodates rope up to 8mm (5/16") or wire cable up to 4mm (5/32")
  • 800kg (1,760 lbs) breaking load capacity
  • Plain bearing design ideal for high static load applications
  • Prevents line chafing when routing through structures

Applications:

  • Halyard systems on sailboats
  • Control line routing through decks and bulkheads
  • Wire and rope applications requiring directional changes
  • Marine rigging systems requiring high load capacity

Constructed with premium marine-grade materials, this exit box delivers reliable performance in demanding saltwater environments. The Nylatron sheave material provides excellent wear resistance while maintaining smooth operation even under sustained loads.

I haven't got my order yet... But praying everything goes well.

Best price I could find, and free shipping. ..I am hoping to get the tank soon

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

Good

Great prices & plenty of products...plan on buying from this site for a long time.

easy pay good prices

good customer service. after shopping around for a while i decided to go with them.

easy

Everything went smoothly

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

Thank you

The price was right, and they were very helpful and told me all about the product I ordered, and had it shipped out to me quickly! <br><br>Thanks!
