Title: "Grapple" type device
Post by: Bonnie Lackey on February 18, 2011, 01:02:09 PM
I posted this on the AV board but am wondering if anyone has used the Grapple for either stage or decor lighting.  I am in no way affiliated with the product but it has given me some creative ideas.  Now if we can just get some bendable truss.

A link to what you are talking about would help.

I've never used it myself but have seen it before.  I've thought about getting some but haven't had a need yet.  They're quite a bit less expensive than corner blocks, so that might be a viable alternative.

I designed and fabricated a similar device about 1o years ago.  I used it in a venue where i had fixed points and needed to build a custom grid to accommodate the clients needs. On recommendation from our structural engineer we down-rated the load on the truss by 1/2 because of the compression on the tube side walls.
We had no issues to speak of when using it.   Eventually we fabricated a custom truss length so we could use a corner block and go to full loading.   They make a handy tool but not a replacement.

Though I have done plenty of concert and corporate lighting, I was excited about using it for decor lighting.  You could use it to make "S"s, "T"s, "P"s, etc.  Using LED lights or Source 4's on the ground, I will feel safe with the diminished load ability.  Bonnie
