Product Information
Automatic ratchet block
Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes*. In the auto mode of 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. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer - you really can't go wrong.
Selected Series 55 models.
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 patented sheave cross-hole geometry. Its holding power is up to 21:1, almost double that of our nearest competitior. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designes have only 8 faces with 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.
Materials
Sheave: Hard anodized Aluminum
Ball Bearings: High compression strength carbon black Acetal
Frame/Cheeks: Toughened, glass fibre reinforced Nylon
Rope Link: UV stabilised, multi-strand impregnated SK75 Dyneema®

Smaller then you think!
Color: Dark Brown
This purse is GORGEOUS!
I just wished it was bigger. I guess that’s my fault for not paying attention to the measurements.
Even in the pictures with the models it looked bigger
Not enough room for me so I sent it back

Shipping department dropped the ball
Color: Dark Brown, Color: Dark Brown
I am ashamed that Amazon would claim to be an outfit that deals in luxury bags. The packaging and merchandise handlers really dropped the ball. The purse was very nice and well made. ( with the exception of the long strap 👎 ) it’s a shame this bag was tossed in the box that way I received this leather bag it was all wadded up and wrinkled in all the wrong places such as a huge wrinkle across the bottom. $139. For a bag that’s looks like it’s been in the corner of someone’s closet for months or maybe like the UPS truck ran over it. Not cool. Luxurious expensive merchandise you would expect at least a little care and packaging and handling. Disappointed

Absolutely soft leather
Color: Coffee
I ordered the coffee color, absolutely love it.Super soft- I have ordered brands that cost 4xs as much & returned because of stiff leather. The zippers simply glide.I love all the different zipper pockets, I like having a place for everything, my phone fits perfectly in the back side zipper area. The front magnetic for my key fob.Zipper above to get out quick cash.I had a hard time deciding which color I wanted! It's roomy enough inside but not too big where Im going to carry things I dont need. It's nice having 2 straps to trade out- im starting with the guitar strap- like that it is adjustable straps & on swivel hooks.And you can really smell the genuine leather. For my preference I would have liked it to have been 2 to 3 inches shorter height wise as I was looking to replace a few bags I used when flying but this is perfect for an everyday crossbody.This bag looks very well made. Nothing fancy on the inside. Plan on searching for this brand in smaller size and some soft colors for spring & summer.

Definitely would recommend
Color: Brown, Color: Brown
This bag had soft leather and looked just like the picture on the product page. There is the main compartment, two zippers and two slip pockets on the inside. I do like the bag, but I don’t usually like slip pockets because a lot of times when you’re just throwing things into the bag items might go into a slip pocket without you realizing it. I didn’t pay attention to this when I bought the bag, but I still really like it. On the back is a large compartment with a zipper. On the front is another large compartment with a zipper and a pocket with a magnetic snap. I bought the brownish color one and it’s really beautiful. I would definitely recommend it. It does come with two straps I am trying out the one they call Boho for now. It is very nice. The other one which I guess is leather also is much thinner.
