Examine a GripStarChute and youll find an incredibly strong 3/8" (1cm) diameter, braided, polyester rope cable. Virtually all the force is exerted directly on the chutes material or seams from the air billowing beneath. A GripStar handle is set inside the hem, rolled around the rope, and then stitched to itself. The result is a 4-layer construction, where stitching goes through the handle webbing, through the first layer of nylon, back through the webbing and out through a 2nd layer of nylon. It does so in a way that places all the force exerted by the handle directly upon the virtually indestructible rope cable. Finally, we upgraded the mesh and stitching of the vent hole, so that it will allow air through, while barring the way for small heads and objects. Handles are placed every 3 to 4 (.9m to 1.2m); participants calculated for every 2 to 2-1/2 (.6 to .8m). GripStars are made of water-resistant nylon. Every chute purchased has an unconditional, 3-year guarantee. 24 (7.3m) diameter with 22 handles. 75-1/2 circumference provides room for 30-37 participants. Category: Leadup Skills / Parachutes.
