Driveway Stake Stringer Cap Fiberglass 8mm

This slides over top of the rod to be able to run a string/cord through them to establish a barrier. Due to the nature of manufacturing tolerances of the stakes, these are made to fit the average 8mm rod. Some may be slightly loose or tight. The age of the rods will effect the fit also. Print one out and test the fit. If its too lose and you want to be able to remove them later then you can elongate the part another 5-10mm for better hold. For a permanent fit just add a dab of glue. Don't try to adjust the ID of the hole. I have played with the fit in increments of .025mm which only makes some too lose or too tight depending on the manufacturing.
