What kind of riser inserts ?

Recommended Posts

I finally got read some of the postings regarding the riser inserts that can help ease the pressure of a cutaway when the risers are twisted up.

I am wondering which you think are best ? I hear they have plastic and metal inserts. Which are better ? Or... are there other types that I don't know of that may be even better ?

Thanks for all your help. :)

I just had it done, and got the metal ones from RW for my Vector 3 rig. I don't have the experience to tell you why metal would be better, it just seems like it would be more durable to me. Plus, it was only $30 to buy them and get them installed, so it's not like the metal ones break the bank.

The sunpath plastic ones are the best plastic ones on the market, but the metal are the best option in my opinion. I've heard of home made ones, but I would'nt come within 50 feet of jumping those since they are not as high quality as manufactored ones.

There is a possibility the plastic ones can be crushed. It's not likely but possible. If you read My overly worded lengthy Post in talk back Poll: Reserve: repack or pencil? I believe that inserts MAY have helped. But given the conditions of the risers and the type of channel it's tough to say.

I am finally inserting metal ones when I get home tonight

in a severe line twist situation, or a hard cut-away situation (for what ever reason) the metal housings provide a rigid internal housing for the cut away lines, thus virtually eliminating the "hard cut away" by reducing the internal friction on the cut away lines on your handle.

I once heard someone argue against metal inserts by saying something to the effect of "...if you were to slam them in your car door or something like that, they could crush..."

I guess they could, but if you're such and idiot that you slam your risers in your car door AND don't check your gear afterwards, I think you have bigger problems.

Metal is easy, they flex well and they fit 3/4 inch cable channels like a glove.

That was SUNPATH saying that :)"New "anti-twist" technology main risers, incorporating plastic riser tube inserts, are featured on this container. The tubes are of a composition that meets, or exceeds, the test conditions required by the FAA TSO. The advantage of plastic tubes is that they can be "crushed" in a car door/trunk, and continue to function."

Sounds like an advantage that will never be taken advantage of :S...

If you do get the plastic ones, make SURE you have them installed by someone that knows what they are doing. The metal ones have a cap on the end which keeps it from sliding down, (But still it is recomended that you have them installed by someone that knows how to also). The plastic ones installed the way Javelin does keeps them in place just fine, but if you just put them in you can risk the insert sliding into your loop and you wont be able to cut away.

All i KNOW is this; 4 cutaways on a Xaos 21 loaded at 2.1:1 with javelin risers with plastic inserts. No problems at all



How many of these were tightly spun - to the point that your risers were part of the twists...?

There is an article, I think in parachutist, last year that Mike Turoff wrote about no inserts - vs. - plastic - vs. - metal. in every test the metal had the losest cutaway force. Plastic and Metal were very close, only a few lbs apart until it came to extreme then the pull force for plastic went up sharply. I'm to lazy to look for the article but it was last year sometime.
Fly it like you stole it!

I have had four cutaways total. Two spun up very hard. Second to last one on my 72sq ft Xaos 27 was sick. I have never seen something spin so fast. I was in line twists during the whole deployment, but once the canopy fully pressurized; it dove straight toward the ground and spun from the top all the way through the risers in what seemed like less than a second. Happened extremely fast. There was so much force involved that it shifted my harness to the point that I struggled for a second to find my reserve handle which was way down on my hip. I have a small rig that I crank the hell out of the leg straps as I fly with harness input. I thought it had flipped under my lift web and was fumbling for it there when I spotted it way down on my hip. Still can't believe it was down there! Opened with a few hundred feet to spare. No riser inserts on any of my cutaways.

That spot isn't bad at all, the winds were strong and that was the issue! It was just on the downwind side.

Little bits of tubing that go inside the riser where the cutaway cable ends. This stops the cable being pinched if you end up in bad enough twists, and allows you a much easier cutaway.

[edit] Won't affect cutaway pull required if twists aren't down to the risers etc.
