Its pretty simple. They work almost like a regular toggle bolt but the white plastic tab is like a wire zip-tie that holds the stainless steel part in place so you can run your 1/4" machine screw (Not a lag bolt) through the tank, through the deck and in to the toggler that would be under the deck.
For the 1/4" size you will need to drill a 1/2" hole to put it through.
Its what I used to hold my trolling motor on the bow of the boat.
They are great when you cant get to the back of your bolt to put a nut on it. Like a pedestal seat in a deck.
Here ya go,,,,ya drill a 1/2" hole through the deck,,,,then you pivot the toggle so it will slide through the hole.
Then you slide down the tab "A" flush with the top of the deck. It holds the toggle in place under the deck (It locks in place like a wire tie).
Then you cut off the handles "B" with a set of side cutters.
All you do then is slide your tank into place and run your 1/4" bolt through the bracket and then down into the toggle and tighten the shit out of it.............
A lot of people dont know about these,,I think they are cool as hell! Saved my ass more than once....
O-Yeah, Im not a big fan of lag bolts in a deck of a boat. They dont last........
