OPERATION

MANUAL MODE
RT blocks leave the factory in Manual mode, with the black MODE switches on both sides of the block positioned away from the red ON/OFF knob.

Use the red ON/OFF knob to turn the ratchet ON or OFF.

AUTO MODE
With the block in Manual mode, turn the ratchet off by rotating the red ON/OFF knob to the OFF position.

Slide the black MODE switch firmly toward the red ON/OFF knob until it locks into the recess in the knob. Repeat with the MODE switch on the other side of the block.

The block is now in Auto mode.

To return to Manual mode, slide the black MODE switches on both sides of the block firmly away from the red ON/OFF knob. Now use the red ON/OFF knob to turn the ratchet ON and OFF.

We recommend using the RF613S shackle to securely attach the block to the existing deck eye on your boat. This helps the block maintain maximum freedom of movement and reduces the risk of wear on the Dyneema loop due to sharp edges on the deck eye, then use the 8072 Rubber Boot to keep the block upright and provide a neat finish.

Just buy it!
Color: Grey, Size: 74"x60"
I'm always cold and wanted a blanky, a goto cuddly blanket! I bought this with the intentions of turning it into a duvet for my heating blanket. Now, I haven't bought a blanket in over 20yrs and then it was just some down comforters where I updated the duvets over the years but that's it. So I started shopping and picked my top 5 faux fur blankets based on fiber density (where available), color, and customer reviews. I was willing to pay as long as I got that goto blanky, I didnt want to be left underwhelmed, especially the more I have to spend. As a blanket newbie I got stuck and couldn't decide, so it came down to customer reviews and price point. There is $600 brand of blanket which im.sure is lovely but I will never know, just crossed them off my list, couldn't justify it, leaving this as the next most expensive on my list. So, I asked myself, do you really get what you pay for? Or all these blankets made by the same company, basically the same with different price tags? After reading EVERY SINGLE REVIEW ON ALL 5 BLANKETS and some others I had crossed out because I'm so terrified of buyers remorse, THIS BLANKET HAS THE FEWEST NEGATIVE COMMENTS OF ANY BLANKET!!! That being said theres a lot of postive comments out there but what if the other blankets positive comments are just from people who've never experienced a REALLY NICE BLANKY??? So I went with highest price point willing to spend (under $300ish) and fewest negative comments from people who sounded like they knew blankets, pics and videos people uploaded, etc. I let go and turned it over to the universe... If you're on the fence because it is pricey, JUST GET IT! It's freaking nice, like REALLY NICE! It's as if not more comfy than my 20 year old ralph Lauren duvet which I spent way more on than this. THIS BLANKET IS AMAZING and IT DOESNT SHED! 1. I'm not a trapper or a tanner but it looks real af to me. Real enough... 2. The fur is long, soft and fluffy! It's like your friends shaggy dog you want to love and squeeze but you know he hasn't been brushed and can smell him when you walked in the door. It's like that but only positive, I never want to leave it , pet it like dog, it's becoming my best friend, and I don't have to walk it! Even the inside is soft! It's like husky on th outside and rabbit on the inside!!! 3. It's warm and It's got some weight to it! Definitely not a cheap throw!!!!! Remember I was gonna use this as a duvet cover for my electric blanket??? Under this alone I sweat! Several times a night i wake up and throw it off me, my electric blanket doesn't even make me sweat and which is why I thought I could use cover for it.... WRONG! This blanket was all i needed! I've already probably said too much, but this Is the first review I've ever written. All I can say is if you're undecided; JUST GET THIS DANG BLANKET, SERIOUSLY! One more thing, to tell the world how crazy my fear of buyers remorse is a week or so ago, my number 3 blanket, leedy much cheper than this, was on ridiculously low sale so I had to buy it too see I you get what you pay for??? And YOU DO! Granted, It's a really nice blanket, and I probably would have been fine with it, HAVING NEVER SEEN THIS BLANKET.... The other blanket soft, shorter hair, looks real enough, sheds a bit so I brush it, but compared to this blanket, well you can't! It's like comparing a howrd Johnson or days inn to the ritz-carlton, or tube hamburger and a filet, one of these blankets you might consider cutting up for a kids costume and the other you definitely would not and its not just because of the price differnce, but in this instance, you do get what you pay for! The other blanket is not like us, hahaha If you made it this far I hope this helps you, good luck, and I'm telling you...

Buy this while it’s priced so low.
Color: Brown, Size: 74"x60"
I am a collector of furry blankets and this one is my new favorite. It’s heavy, and really warm. It’s also a beautiful blanket with the hair tones differently than I’ve seen before. Thank you for the high quality and a relatively lower price than other of close to the same value. It’s so soft and beautiful I had to buy another one!
