Neo Throw Weights have a proven aerodynamic design that out-flies other shapes. Combine that with our new high-visibility colors and enhanced durability and you;ve got a throw weight made for launching. The new SHERRILLtree Neo Throw Weights come with a narrower "D" style steel ring to attach your throw line. Neo Throw Weights are standard with a webbing loop on the bottom for quick attachment of a climbing or rigging line. The Neo Throw Weights are covered by a 6-month material defect warranty. If the throw weight fails under normal usage we;ll replace it at no charge. The Neo Throw Weights come standard in 6, 8, 10, 12, 14 and 16 ounce weights.
