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.

Soft and they are good for my sensitive skin
Size: 300 Count (Pack of 3)
These are the only cotton rounds I do not break out with. I use them to cleanse my eyelids along with micellar water for my face. They are great!!

MUST HAVE for me!!
LOVE LOVE!! These are most perfect for make up removal and I use them to apply toner as well. Soft and cushiony. I have tried other styles and they don't compare. There are durable, don't shred when you use them like traditional cotton balls They don't "pill" on your face when using them.

Best Cotton "Pillows" I've Ever Used
How much do I love these soft, thick, and durable cotton pads? I got tired of running out (I use them every day) so I ordered a carton with packages of 100! So simple to use...there's a tiny "pocket" on one side you can put your fingertip in for accuracy, if you choose! They soak up enough nail polish remover to do the job, but are so strong they don't shred like a cotton ball would.

The best gentle pad
I use these constantly to clean my Chinchilla Persian Cats nose which is always leaking. These pads are gentle on his nose and don't shed which I luv. There"s a little slit on one side to use if you want to slip your finger into to hold. These pads are soft on both sides. I dampen them before using. The shape to me is better than the round pads and also the edges are not rough like many round pads are.
