Review: Classic, Bulletproof Harken small boat gear - It works very well. I have used this particular block on small boats since I learned how to sail 36 years ago. There doesn't appear to be any "value engineering" going on. It's just as robust and durable as it ever was.

## Questions & Answers

**Q: Except for rollers, Is the 22mm all stainless.  Are the ball bearings sealed.  I want to use it off shore**
A: The best I can tell they are all stainless except rollers. I can't answer about the bearings but I have used mine on my Hobie 16 for years in a saltwater environment and so far they have performed flawlessly. Hope this helps.

**Q: Can I use this with a 1/4 '' line?**
A: yes

**Q: What is the diameter of the mounting holes?**
A: The mounting holes are .20" or 5.17mm

**Q: is the becket pin removeable or is it "riveted" in place?**
A: riveted

### ⭐⭐⭐⭐⭐ Great small block
*by C***C on August 8, 2025*

Best block I've found in this small size. Smooth running, it has a swivel attachment that self-adjusts to the direction of pull. Expensive but worth it.

### ⭐⭐⭐⭐⭐ Classic, Bulletproof Harken small boat gear

### ⭐⭐⭐⭐⭐ Excellent Harken Quality
*by M***R on October 7, 2024*

I have used these several times over the years. Great for an anchor trolley system on a kayak. I like this because it doesn’t flop around and bang the side of the boat. Much more stealthy! A little silicone spray a couple of times a year and it’s worry free.
