I don't know much about these as I got them with a garage clean out.  Lot of 18 Never Installed / NOS EPC Brand Copper Pipe / Tubing Straps with Two-Hole Clamps Mounts as shown.  These are non-magnetic, so I assume they're solid copper versus just being plated.  The width of each measures approximately 2 1/4" long, so I'm not sure what size pipe that equates to.  These have never been installed, but have signs of sitting somewhere (i.e. scuffs, surface corrosion, scratches, dirt, grit, grime, etc).  Please see the pictures as they are part of the description.  Again, check to make sure that this will fit your application (plumbing, crafts, etc).  What you see is what you get.  Look the pictures over and judge for yourself!

AS WITH ANY ITEMS, NO RETURNS ACCEPTED.  Item is for sale locally, so I reserve the right to end listing early.  International buyers through E-bay's global ship only.  It will take a few days to get item shipped.  Please let me know if you have any questions.  Thanks for looking!
