Here is a cool observation we've made by looking at our internal sales statistics... Our best customers have one thing in common - they use swivels on their parachutes. Go figure. Obviously, they know that quality swivels pay huge dividends in getting a rocket back with no damage.
Swivels, like the fishing-line variety, are commonly used on small rockets to reduce the amount of twisting in the lines of parachutes. But most people don't know that high-strength barrel swivels are available for all sizes of rockets. Better still, these swivels have ball-bearings in them, so they spin much easier than the small ones you may be used to using that you got from your local store. That means your lines will stay straight and the parachute canopy will be fully inflated during the entire descent of the rocket. Because of that, the rocket will land slower and softly on the ground and reduce the chances of it getting dinged up on landing. Won't that save you some money in repair costs?
The other thing about these swivels is that the rings on the ends are welded closed. That way they won't pry open like a key ring when the parachute opens and the weight of the rocket is transmitted through the swivel. This gives you the confidence that the rocket will come down in one unit, rather than separating like those cheap starter rockets from other companies.
If you're the type of person that loves a successful launch from lift-off to touchdown, and you enjoy when things go as planned, then these parachute swivels will give you confidence that your launch will be the hit of the day.
INCLUDED - two pieces of 100# Kevlar line. This is included because the loops on this small swivel are very small. You'll need to tie a piece to each end of the swivel so you can attach it to your rocket.
Features Include:
- Highly polished stainless steel ball-bearings
- Welded stainless steel rings

We recommend attaching the parachute directly to one end of the barrel swivel, and the other end looped with a quick-link. The quick-link can then be attached to the shock cord, or to the base of the nose cone.
Note: Parachute, shock cord, and quick-link are not included with the barrel swivel. Shown to explain how the swivel might be used.
