Why I Preach About Using Hollow Blocks for Aerial Sling Rigging

If I could take back the first 5 years of my aerial performing life I would. I would take back the frustrating hours I spent trying to untie the incredibly difficult knots that became the ends of my aerial hammock. I loathed washing my fabric just because I knew I would have to fight them. I would take back the extra hours of "wiggle room" I gave myself before gigs to make sure I had enough time just to set the height that I wanted ( because it was never perfect and I would have to tie/re-tie my knots to get it just right). 

I preach to every aerialist I know that they should be using hollow blocks to tie their aerial hammock / sling. Why? I'll tell you why! But first, let's talk about a few common hammock / sling rigging techniques...

1. TYING DIRECTLY TO THE CARABINER

This is an absolute "no." If you are using carabiners to tie the end of your aerial hammock / yoga / sling...STOP. RIGHT. NOW. There's plenty of rigging information available now that will tell you why this is a bad idea. #1 first and foremost--the fabric tied this way will overload your carabiner. Vertical Art Dance has a great video explaining how this method can overload your equipment. 

2. TYING TO AN "O" RING

While this method is acceptable and considered "safe," there are many reasons while I will never use an o-ring to tie my aerial hammock rigging ever again. Most of these reasons could apply to using a Rescue 8 as well. Here are just a few of my personal reasons, counting down to the most problematic.

Reason #3 - Heavy, Clunky, Loud

I like my apparatus to be soft & quiet. O-rings are bothersome to me because they can create loud, clanking noises if they are hitting other pieces of metal hardware. They also make the ends of my hammock heavy. I can't drop my fabric on the ground because the o-rings would hit, causing damage to the rings and to the floor most likely.

Reason #2 - Impossibly Tight Knots

It's been a month (or more) of use and it's time to wash your stinky fabric. You go to untie your knot and it takes 6 hands and 45 minutes of tugging, pulling, possibly even cutting your fabric. If you rig your own equipment, which I hope you do, you know exactly what I'm talking about! This is the opposite of problem #1, obviously.

Reason #1 - Knot Failure

This has never happened to me personally, but I have seen multiple aerialists through the internet and/or in real life (many of them who are "advanced" "experienced" "teachers" etc.) fail to tie off correctly to the o-ring. What happens when the knot is tied incorrectly? It slips! You do not want your hammock just slipping right out from underneath you when you perform or teach! It's terrifying and it's dangerous. My first year in aerial I watched a performer's knot come untied and she was left with one silk dangling from the ceiling. I was new and completely confused because I thought maybe it was part of the act (I didn't know any better). Later on I learned what had actually happened and since then I have seen this happen as one of the most common rigging failures in the industry. 

So now that we have covered those two tragedies. Let me present to you, the unicorn of aerial rigging:

3. PRUSSIC (FRICTION HITCH) USING HOLLOW BLOCK

In 2016 I taught at the Vertical Art Dance Zion Aerial Arts Retreat and it was in that weekend I was bestowed my first ever pair of hollow blocks. They literally changed. my. life. Here's why:

EASE OF USE

Once you know how to wrap the hollow block onto your fabric & practice a few times, it becomes incredibly easy to do. I can install and remove my blocks in a matter of seconds--which makes laundering my fabrics a breeze! Hollow blocks also make it extremely quick and easy to adjust height. I don't event have to remove the hollow block from my hammock at all! I can hold the entire piece of equipment in one hand and slide it "up" or "down" to adjust the length of my apparatus.

INCREDIBLY STRONG & SAFE (BASICALLY FOOLPROOF)

Like I said, it's so easy to install it's basically foolproof. If you weren't a boy scout, don't worry, you don't need to know how to tie any fancy of knots to use this equipment. The material will not melt like traditional nylon or polyester. It is extremely strong & heat resistant (chars at 950 degrees).

While you're at it, check out VAD's other rigging safety resource videos too! They have tons of free information available to the aerial community. 

SOFT, LIGHT & QUIET

My soft hollow block rigging doesn't make noise against the other hardware on my apparatus. I can drop my fabric on the ground (after detaching from the metal hardware) and it doesn't make any noise or damage the equipment. I also really like the fact that my hollow blocks will not put wear and tear on my carabiners the way that a steel o-ring would over time. 

MAKE DUAL-COLORED TWIN TAIL SILKS

You can use hollow-blocks to make twin tail silks that are two different colors! This could be purely for aesthetic purposes but it's also useful as a teaching tool. (i.e. "grab your blue fabric and wrap behind your back. Now tie your foot with the green fabric")

AFFORDABLE

$12.95 - $14.95 per hollow block through Vertical Art Dance AND if you use my code "hollyannjarvis" you get $10 off your entire order! That's a steal. For under $30 per hammock / sling set-up, you can have peace of mind and an amazing piece of equipment that will save you time and unnecessary frustration when it comes to rigging. You're welcome! :)
