Increase install speed and precision with our 10 mm swab guide.
Primer 94 is fantastic—but it can be too powerful when it strays past the finish line. Excess primer can leave adhesive residue and even damage delicate surfaces. This simple guide controls your pass to exactly 10 mm, helping you keep primer only where it’s needed.
Quick to use and easy to clean. For best results, don’t overload the swab.
