These target holders are designed to work with the Brunson Invar System.  On one end, a 3/8" x 24 external thread mates to our standard Invar System tubing.  The other end provides a slip-fit holder for targets having a 1/4" shank.  A brass thumbscrew allows you to secure the target without gouging the shank.  The "effective length" is held precisely to 24mm (14158) or 1.000" (14159).  This item is supplied with a spare thumbscrew.  You can read about other Invar System Components on this website.
