My Tapered Elliptical arm. 10 feet I think. Pretty big. Not all that heavy though. xD I am not sure why this fell off the pole. Or did it fall off the pole? I can't wait to put this up tomorrow and mount a light on it. How does it look? Anyone know the brand? I could guess GE but there isn't any brand name on it... Keywords: Gear

Aluminum I assume? Don't you have a tape measure that you could measure it with? I'm not sure but this looks more like a 8 footer to me. I know these are very light, I have held a 8 foot and a 10 foot arm and both weighed barley more than a few pounds.
LilCinnamon   [Jan 28, 2012 at 03:07 PM]
I hung this up outside for a bit, I wish I Had better screws that could support the weight! D:

And I have one but it's not on me at the moment. I will measure it later.

And this is pretty light, it makes installing the arm much easier.

When it get's warmer outside I will mount a light on it and take a pic.

I would suggest lag screws, they are what are really used on wooden poles along with a through bolt.
streetlight98   [Jan 28, 2012 at 03:48 PM]
Yes. DO NOT hang this up with any lights on it until you get a thru-bolt. Without the thru-bolt, you'll loose another light. Shocked
LilCinnamon   [Jan 28, 2012 at 03:58 PM]
I used a lag screw, it was a long screw.

The first screw was too small so the screw popped right out. But I don't plan to do much with this yet anyway.
gailgrove   [Jan 28, 2012 at 04:04 PM]
A large lag screw would hold it up, temporarily anyways. However a through bolt would be the only way to
be sure it wouldn't fall is a through bolt, you wouldn't neede to remove it either, just install it the first time and tighten it when needed.
LilCinnamon   [Jan 28, 2012 at 04:10 PM]
For a through bolt I would have to ask IREA about it. I wouldn't know how to install it and I bet they would be the only ones who have the tools.
gailgrove   [Jan 28, 2012 at 04:13 PM]
It is pretty simple, you drill a hole through the pole with a large bit and put the bolt in, sometimes it requires a bit of hammering to get it in.
joe_347V   [Jan 28, 2012 at 04:15 PM]
Make sure you use the proper sized washers with your through bolt, or the bolt will start digging into the wood and cause the arm to sag.
streetlight98   [Jan 28, 2012 at 04:16 PM]
A thru-bolt is basically a huge screw with a nut on the end. You drill a hole through the pole and install the bolt. If you have a pair of binoculars, look closely at how the thru-bolts are attatched in your area.
joe_347V   [Jan 28, 2012 at 04:17 PM]
Yeah but the other end will start to dig in to the wood if you don't use a big enough washer. Wink
streetlight98   [Jan 28, 2012 at 04:20 PM]
You should always use washers anyways. Razz
gailgrove   [Jan 28, 2012 at 04:20 PM]
Here big square washers are used, the arm side shouldnt have a washer so you can lift it on and off of the bolt head easily.
joe_347V   [Jan 28, 2012 at 04:20 PM]
I know people who don't Rolling Eyes
streetlight98   [Jan 28, 2012 at 04:22 PM]
The big square ones are used here too. Some of the truss arms here have two thru-bolts. Shocked
joe_347V   [Jan 28, 2012 at 04:27 PM]
Sometimes the utility will get lazy and only use one bolt on a arm and instead will strap the bottom on using band-it. Shocked
gailgrove   [Jan 28, 2012 at 04:33 PM]
I've seen the before as well, it doesn't really bother me but this does, it is an arm held on by nothing but band-it. Shocked

On RIDOT's aluminum truss poles, the arms are attatched to the pole with these shown below:
joe_347V   [Jan 28, 2012 at 05:47 PM]
I've seen those too, they're common in older MTO installs.
gailgrove   [Jan 28, 2012 at 07:41 PM]
Yeah I've seen those used with the MTO truss arms as well.
