I've got that 8701W from Grillstuff and can confirm that 1: it is an excellent cover. Mine has held up well for 3 years outside (under an eave) so far, and has a lot of life left in it and 2: it fits my SSP with the newer larger lid bale. It is snug, but not too tight. It is actually a really nice fit, although I would not want it any tighter.
