HAMMOCK KIT - SCREWS Made In The Shade. You have an overwhelming need for an al fresco nap. Luckily, you have a hammock, and (2) healthy trees (8" dia or larger) or (2) pressure-treated posts (6" x 6" x 6 ft or larger) Seems to us that (1) tree and (1) post would work, but Eastman Outdoors is pretty strict about following the directions. They need to relax. Maybe they ought to buy a hammock. If they do, we'll sell them this set of (2) 4-1/4" long x 3/8" dia steel eyes that screw 2" into the trees or posts. Attached to the eyes are 3/8" dia "S" hooks. To these they could attach the set's heavy 25" chains made of 3/16" dia welded links that end in more "S" hooks and support the hammock (up to 300 lbs) Whew! It was more work to write than to hang. Nap time! Click on the accessories link to see other items mentioned in this description.
