This is a 4" long steel rod with 1" of thread on one end which has 2-56 sized threads. A Great Planes nylon clevis is then threaded onto the rod. This clevis snaps to close and has the added advantage of a hex-shaped shank to allow a wrench to be used to screw the clevis on and off the rod. The clevis retainer prevents the clevis from opening unintentionally. INCLUDES: One 2-56 x 4" rod One nylon clevis One clevis retainer One 1" solder on split coupler REQUIRES: 5/32" hex wrench for the clevises 4/17/94 RDT ir/jl
