Mini Ball Anti-Zipper Kit
Even your smallest rockets can zipper. So why not protect them with a
Black Cat Rocketry Mini Ball Anti-Zipper device.
Sized for Mid-power rockets.
The kit includes:
- Small Kevlar sock
- Foam ball to absorb the shock cord stress to the airframe wall
- 2 cable ties to secure your Mini-Ball to your shock cord.
Assembly is simple.
- make a hole in the foam ball for your shock cord
- pass the shock cord through the ball
- fit the Kevlar sleeve over the ball
- adjust the ball position so when the shock cord is at its full stretch position 1/2 of the mini-ball is above the edge of the airframe (see below)
- attach cable ties and trim cable tie ends
