Re: Got a free trampoline; how do I stretch the net?
Some trampolines come with a hook on a handle, used to grab the pad hooks and pull them towards the slots.
If you don't have the hook, I have had some luck tightening a pair of vise-grips, on the backs of the hooks and use the VG to pull them towards the locking slots.
Get ready to swear, when they slip.
