Replacement blades for Beiter Compound rests.
Tip widths come in three sizes
4mm - For small diameter arrows like CX Nano Pros and Easton Protour
5mm - Same size as Trophy Taker narrow blades. Suits everything
6mm - Wider for those shooting lareger arrows like CXLs or indoor arrows.
Thickness determines the amount of spring in the blade. Lighter arrow may be better off with a softer blade like the 0.20mm blade while a heavy arrow may like the 0.30mm blade. The 0.25mm should work with everything.
