To prevent this you have to take a couple of steps. First, remove the trampoline. OK, this part is easy, but putting it back in kind of sucks. Pad the track with something, wood, paper, something and use a few visegrip type plyers to squish the track grove smaller. Before reinstalling the tramp, intall four corner gromets near the edge of the bolt rope at each corner of the rope slide portion. Then re-install the tramp. Pull snug, then drill a small hole next to each forward gromet in the aluminum track. This hole should be just big enough to place the pin of a small shackle in (use the bell portion of the shackle as a guide, pin and ring type only). Place the bell of the shackle in the gromet and secure the tramp to the track(ring side down to avoid snagging). Now tighten the tramp and drill the same hole at each rear corner. Secure the shackle and you should be good to go. If the tramp pulls out again, it will be limited by the shackle.
