Need help locating U.S. vendor of tarp poles, guy ropes, guy rope springs

[Night Train]

Thanks in advance everyone. I'm putting together a tarp kit to be used over my tent/tentcot/hammock, (whichever this weekend dictates), and my kitchen area. I've got several tarps, but my attic search revealed that I remember now throwing away a few years ago a accumulation of 35 years worth of tent/canopy bits and pieces that I now need...for the said purpose of having on hand the parts to erect any tarp configuration a person would ever want. At the time it seemed like a good idea to clear the clutter up there. Now it doesn't. I have found the extendable poles (like those on the old Coleman canvas tents) I need, but I can't find a domestic vendor that has the guy ropes and springs I need to do it right. Any ideas?


Also, anyone know a vendor selling larger size cantenary-cut tarps? Like 15X20, or larger. Nothing like your plastic tarp snapping back and forth in the wind all night to make the campground love you in the morning, is there? Thanks again!
