Zapper 400 Replacement Fins (4 fins) with 4 Smoke Quiet Tape Strips. Choose either 0.015 or 0.023 fin thickness.
Rests come standard with .015 thickness fins. There are also .023 thickness fins available. Sometimes shooters feel they shoot better groups with a thicker set of fins. Other times, the thicker fins may be preferred by archers using heavier arrows (over 500 grains).
0.015″ thickness (arrows under 550 grains)
0.023″ thickness (arrows over 5500 grains)
