Is this a pair of back straps or just one?

It is a single backstrap.

Is this the same as the strapping material used in attics to support duct systems? I have a roll of that material. It is pretty thin.
[ Ken  Apr 07, 2018 ]

No, it is a thicker material than duct strapping.
[ Paul  Apr 16, 2018 ]
It's narrower than hanger strap and heavier gauge material. I believe the purpose is to support the back of the audio unit so it doesn't sag or bounce around. I bought one just in case I needed it but turned out that I didn't.

What tool did you use to cut this?
[ Chase  Jun 03, 2017 ]

I used a pair of tin snips. You can also use wire cutters.
[ Douglas  Apr 12, 2019 ]
Actually, I bent it back and forth until it snapped in-two

How long are these?
[ DustinUnknown  Nov 05, 2015 ]

Maybe 9 to 10 inches.
[ Paul  Apr 16, 2018 ]
6 -7 inch almost always cut them in installs
[ michael jonas  Jan 02, 2016 ]
Pretty long. I used all mine, but I'm guessing they're around 7in. I had to cut all of mine when using them for installing tweeters.
[ Jestep  Nov 06, 2015 ]
If the tweeter has empty space around it while using a backstrap, does that empty space need to be filled? also, should there be some sort of vibration dampening material between the tweeter and the backstrap and the backstrap to mounting screws?
[ John  Jul 01, 2015 ]

Agree with above. Only lower frequency speakers (bass) really need the acoustic backing to push the sound forward because a good deal of the bass experience is the air movement. Tweeter frames don't rattle from the sound vibration (as there is extremely little) but will if they're not mounted snug.
[ Christopher  Jun 06, 2017 ]
depends if the speaker is a free air speaker or if it has requirements for enclosure space. most tweeters don't require a specific enclosure volume. also, the high frequencies produced by tweeters shouldn't shake much, if you hear or see rattling in you specific case simply put a rubber washer in between
[ michael jonas  Jan 02, 2016 ]
John M. The empty space doesn't need filling; however if you are driving on roads that are rougher than normal(off road) or driving a tractor trailer I would suggest using some rubber bushings between the washers and the strap, and the washers and the mounts for the tweeter. Hope this helps
