The new style Medi-Dart Plastic Wing Nut (MDWN) replaces the old style Short/Small Nut (MDSN). The new Wing Nut and Half Moon Push Rod set up allows stickier needles and better ejection. Medi-Darts are tools for giving intramuscular or subcutaneous injections to livestock without the need to restrain the animal. MDWPR
Note: The old style Small/Short Nut will remain available.
Medi-Dart's unique needle design holds the dart in the animal until the medication is delivered. Once the injection is complete the needle is pushed out of the animal by our patented system. Low stress on your animals.
