HD stands for Heavy Duty. The new WAVE GRENADE HD has 36cm of adjustment for better compatibility with our wave sail range. We analyzed the need for more reliable tubes over this increased length and tested a variety of Aluminum specification. We decided on a wall thickness 33% thicker and an increased outside diameter, for the ultimate durability against bending and breaking.
