This adapter assembly will fit all of our Lurecraft injectors 2oz, 4oz & 6oz that we stock. Assemble and used according to instructions and your baits will come out with one color on one side and another on the opposite. It is amazing how the plastic knows which way to flow and even tentacles on a craw dad will be half one color and half the other!!! INJECTORS NOT INCLUDED. If you are wanting to do a swimbait you will need to use the 2x218 (item 6759) adapter, not the adapter that is sold in the kit.
