I bought my Robbins top from Roadster Factory in 1989. It came with no instructions but they were very helpful over the phone. I still couldn't visualize what John Swauger was trying to explain to me, even after 3 times. So he mailed me a sketch showing how to do it. He was very helpful. It worked and I have had no issue with it since.
Basically I had to take a hammer and a 1/2" diameter round hole cutter and I had to stamp holes into the depressions you show in your photo. These line up and fit over the hex base of all the pegs along the top of the windscreen. Then you fold it back and push down on the outer cap of the retainer onto the peg.

BTW In the last 18 summers of driving 100,000 miles, I would guess that I have had the top up only 4,000 miles because of rainy weather. It's always stored in the trunk, in the bag I bought to keep it nice and clean. In fact, it has been up more often at TRA and VTR concours judging events than when I needed it because of bad weather. You can imagine that if it's raining out and I need a loaf of bread, I'm not going to put the top up and use the TR3A. But when I was away for 3 weeks to VTR in Portland Oregon (7250 miles driven), I didn't put the top up during that 3-week trip except for the judging.

I'm a bit embarrassed to admit that I simply tucked mine up against the fasteners and hand stitched the ends so it wouldn't tumble loose. I was rather proud of this solution at time--maybe fifteen years ago. Oddly enough, it worked rather well. But I'm happy to be corrected.

I still have the original top which came with my 1958 TR3A new on a shelf in my garage. It didn't have this sort of flap. It had a piece of tan coloured fuzzy strip (fur-flex) with a central rubber type of tubing inside which was sown all along the top and which sat snug against the chromed frame to keep the water from coming in along the top.
Neither one will stop all the water. But there is something you can do to minimize the water infiltration or flood. As you drive forward and the rain comes down vertically, there is a vector component that results in the water angling towards the windscreen and when you add the aerodynamics to it, the rain actually gets swept upwards to the top of the glass.
If you have not sealed the gap between the glass and the frame along the top, this upward sweeping rain water will be forced into the gap, over the top of the glass in the chromed frame, inside, and straight down onto to knees. It may not be the top at all.
By the way, that's why it's called a "windscreen". It deflects the wind. No-one ever called it a "waterscreen" to stop the water.

You can watch the water dance along the top of the windshield, searching for entry. And finding it.
I found, however, by living several times in unpleasant climes, that if you leave your top on some of the time, it will, like a glove, begin to conform to the shape you've assigned it, and will even begin more effectively to repel the water.
I know this is bitter advice for most Triumph drivers.
