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.

Sturdy heavy duty plates
Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls)
I have bought these Dixie plates for a few years. They are very good, sturdy plates. I also have the bowls to match. Plates are sturdy and will not bend like regular paper plates

Save Sanity (and Sinks)
Style: 20 Ounces, Size: 56 Count
These 20-ounce bowls have been a lifesaver for a big family with no time—or sanity—to spare for a sink full of dishes. Don’t fill one with water and leave it overnight unless you’re running a paper-mâché experiment. For hot soup, I’d recommend using two bowls, but for cereal, pasta, snacks, or fruit, they’re perfect. I even found one that had been left outside in the rain for a few days and it still hadn’t disintegrated—so sturdiness gets bonus points. Also, three scoops of ice cream plus toppings? Tested and verified. If you value your peace of mind more than your dish pile, these are the bowls you’re looking for.

These are great
Style: 20 Ounces, Size: 56 Count
These hold my hot and cold foods with no problem. I have not had an issue with leaking and it’s been safe to use in the microwave. I’ve even had liquidy foods in it. Like juices from the food. I have also eaten soups with no issues. Great price and durable.
