Series 40 Ratchet Orbit Block - Single - Auto - Swivel Shackle Head

Automatic Ratchet
With automatic models, the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers.

Awesome Ratchet Block Holding Power
Quite simply, Ronstan Ratchet Orbit Blocks have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competititor.

The unique sheave design has 8 gripping faces which directly resist loaded line movement. Traditional designs have an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.

Simple and Secure Attachment
The Dyneema Link is easily fitted and is retained securely by a moulded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shackle pins.

The system is compatible with Dyneema/Spectra strops, webbing and carbon connection points - much more so than steel loop tops or shackles.

Smooth Easing of Sheets
With auto models the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages.

Low Profile Stand-Up Kit Allows 0 or 90 Alignment
Stand-up kits feature a clatter-free rubber boot. You can attach the Dyneema link so that the block is aligned with the stand-up base or across it. It's a neat low-profile solution which allows full articulation.

Exactly what I needed
These are solid and work really well. They’ve held up perfectly and as long as I don’t lose them I can’t imagine them wearing out for a really long time.

Step up your fresh breath game!
This!!! This is the step I was missing in my oral care routine. I was previously using one of those cheap plastic little scrubbers you get from the dollar store to brush my tongue but didn't feel like it did much, it was just a routine. A friend of mine suggested a metal tongue scraper and said it was really helping to keep her mouth clean and fresh after a bunch of expensive dental work. Well, shoot....why not? I won't pretend like I know all the scientific benefits behind tongue scraping, but all I know is from the first time, I was sold on it. You simply hold both ends in your hands and gently place the curved groove on the back of your tongue towards your throat, scraping gently down towards the tip of your tongue. You'll be shocked at the amount of goo that comes off! At least I was, and I am a daily tongue brusher! Rinse the muck off between each scraping and your tongue will be clean and neat. 2 points of caution: 1) Be careful going too far back at first. It can trigger your gag reflex so only go back as far as you feel comfortable and work your way back. 2) You have really sensitive large taste buds at the base of your tongue, so do not press and drag too hard. You can use a small amount of pressure, but not too much is needed. You can definitely hurt your tongue that way (I did, and it was not nice). I've noticed that my breath is much fresher for much longer on days when I scrape my tongue with this. (I did a control test with my old plastic brush and this steel scraper, and the steel scraper outperformed by a mile). My mouth felt cleaner and I don't know if this can be proven, but I feel like food tasted better? My morning coffee seemed even more enjoyable after my first round of tongue-scraping. You get two for such a good price and it will last such a long time. Get one for you and your SO. To be honest, all the brushing and flossing, and mouthwash in the world doesn't replace scraping all that gunk off your tongue if you want fresh clean breath. I highly recommend it.
