These jigs are designed to help get a full pull down of your kydex in the center channel of your mold making the folding process much easier. When the kydex is fully seated on a mold it makes the fold turn out even and clean. We have a small and large version. Small will fit all single magazine molds, while the large will work for all double molds. small is 3.5", large is 6.5" long. These can be easily hung right near your press for easy access and prevent you from misplacing that block of wood that's just laying around that you can never find when you need it.

Does its job well. Like all of Dave's tools/molds, it is well thought out and made.
Good stuff as always from OxCreek 👍🏻👍🏻
