Convert almost any catapult to the FastFix System. If your frame has room for 10mm holes you have room for the BloodShot fast fix band system. Simply drill out the hole, insert the bands, insert the plugs and trim any excess and it is job done. No more tying bands - just insert and tighten.
They will not break like some "flip clip" systems do if they are tightened a little too much. No need for a specialist frame, use the catapult you are used to. Makes band changes in the field a doddle.
Pack contains two plugs, two set screws and two nylon washers.
