Let’s Talk About Ronstan Wire Block w/Removable Clevis Pin Head
The Ronstan Wire Block w/Removable Clevis Pin Head is a seemingly small, yet critically important piece of equipment for sailors, riggers, and anyone working with wire rope in demanding environments. This unassuming block, manufactured by Ronstan, boasts a design focused on durability, ease of use, and reliable performance. Its key feature, the removable clevis pin head, allows for quick and simple attachment and detachment.
I was looking for a replacement block for my sailboat’s backstay adjuster. The old block had seized after years of saltwater exposure, making sail trim difficult and frustrating. I needed a block that was both robust enough to handle the constant tension and easy to service, given the harsh marine environment.
My first impression was positive. The block felt solid and well-made. The Grade 316 stainless steel cheeks were noticeably sturdy, and the Nylatron sheave spun smoothly. The removable clevis pin was easy to manipulate, and the overall design looked both functional and aesthetically pleasing.
Compared to cheaper blocks I’ve used in the past, the Ronstan felt significantly more robust. I also considered a Harken Micro Block, known for its low friction, but decided the Ronstan’s focus on durability and ease of maintenance better suited my needs. It also seemed more appropriate in comparison to a similar sized Wichard block that had more complex construction.
I was immediately excited to install the Ronstan Wire Block w/Removable Clevis Pin Head and put it to the test. This promised to improve the performance and reliability of my backstay adjustment system.
Real-World Testing: Putting Ronstan Wire Block w/Removable Clevis Pin Head to the Test
First Use Experience
I tested the Ronstan Wire Block w/Removable Clevis Pin Head on my 32-foot sailboat during a weekend regatta. The conditions were challenging, with winds gusting up to 25 knots and choppy seas. The block was used on the backstay adjuster, which is constantly under load during sailing.
The Ronstan performed flawlessly. Even under heavy load, the Nylatron sheave spun freely, making backstay adjustments smooth and easy. The removable clevis pin made installation and removal quick. There were no signs of binding or excessive wear after the first day of hard sailing.
I did notice a slight whistling sound from the block at high wind speeds, but it didn’t affect its performance. It was just the sound of air passing through the narrow groove designed for wire rope.
Extended Use & Reliability
After several months of regular use, the Ronstan Wire Block w/Removable Clevis Pin Head continues to perform exceptionally well. The stainless steel cheeks show no signs of corrosion, despite constant exposure to saltwater. The Nylatron sheave remains smooth and free-spinning.
The block has proven remarkably durable. It has survived several offshore passages in demanding conditions without any issues. Cleaning is simple; a quick rinse with fresh water after each sail is all that’s required.
The Ronstan Wire Block w/Removable Clevis Pin Head far outperforms the generic blocks I used previously. This is due to its superior build quality and thoughtful design. It provides smooth, reliable performance in demanding marine conditions, and should significantly improve the longevity of my rigging system.
