You can get them in various lengths and also square as opposed to the round ones that you have.
I recommend that you purchase a square one for your 20 x 30 tarp as they are stronger in construction and perform better over greater lengths. The one we have comes in 3 pieces giving you two areas of adjustment as opposed to one.
There is actually another thread on this forum that explains them in more technical terms and why they are better. (not written by me)
The ones you have are fine for an annex or small tarp but nothing too big, definitely not your 30 x 20 tarp.
We have found that with a bit of wind the L bits will actually pop out of the ring that they go into on the side of our camper and have bent them slightly to try and overcome this. We also do not tighten them off completely so that there is a little more flexibility in them when it is windy.
It is better but not the complete answer.
