Long Arm Here's a shot of a streetlight mounted on a long arm that's normally used for traffic signals instead of using a streetlight arm.

I know of some places in Halton with this setup too.

Interesting Smile

Interesting...how long are they? In my area we have a lot of truss arms on wooden poles in a normal type mount (not a clamp mount) and they are 20 feet long (6.096 meters)
gailgrove   [Jul 16, 2011 at 11:35 PM]
I think these are 12-14 feet long, they can be as long as 22 feet though.

Most of the arm we have around here are 15-20 feet long..... my electrical company uses standards of 30 inch, 10 foot, (and i suspect they started using 12 foot), 15 foot and 20 foot for the wooden pole installation....

However for the Maryland State lighting, on a metal pole...they have the longest arms I know of...and they are 30 feet! But someone may have found a 40 footer up in Canada..I believe

Jace it was me that found that 40 foot arm, and it was in Michigan. Here we use 6, 8, and 10 foot tapered elliptical arms as standards but I have also seen 4 and 12 footers installed before too, not to mention the few other designs and sized installed formerly.

I believe these are Al-Struct traffic signal arms, I guess this around 15 feet long based on the scene pic.

Aluminous also makes the same type of arm with the same design.
joe_347V   [Jul 17, 2011 at 12:45 AM]
I guess the only way to find out is to climb up and check if there's any markings on the arm Laughing
GullWhiz   [Jul 17, 2011 at 02:28 AM]
Joe....markings aren't always found....for example...the older 20 foot truss arms on wooden poles I have found in my area doesn't have any markings (I have seen one up close) and I have been trying for a long time to find out who made them...I already knew the newer ones were made buy Curlees....but the older ones, I recently found out! It's HAPCO!

That's true I have a feeling that this arm design MIGHT be a Powerlite design since Al-Struct bought a lot of Powerlite's designs but I can't find any more info.
