Oh, so only the genus Harpactira makes hammock sacs, I thought perhaps others did too. Thanks!As was said, the Harpactirinae lay hammock sacs.
You then get Heteroscodra, Stromatopelma and Encycrotella that lay fixed sacs.
The hammock sac (like its name suggests) looks like a hammock. Fixed sacs are attached to the inside of the spiders hide, so also can't be rotated either.
