Double Y Posted September 10, 2015 Share Posted September 10, 2015 This is a sign I installed yesterday.The sign is 6 foot tall and 8 foot wide. This is a 3 layer sign. There is a piece behind the wording at the bottom. All made from 10 gauge. The sign itself weighs over 450 pounds with the legs. The vertical rock is over 12 and a half foot tall. It weighs north of 4000 pounds. We dug a hole to set it in. The butt end measured about 24 x 33. We put in about 600 pounds of concrete around the base. The sign has 4 adjustable legs to allow for the difference in the rock and attachment. I am going to add a support leg yet from the back of the sign down to the ground. This is in a high wind area and I think it will benefit from a bit more support. The sign is on the Arrow Creek Exit just off I-90 East of Billings, MT towards Hardin, MT.

ThomasPowers Posted September 10, 2015 Share Posted September 10, 2015 That was my first thought too, out here a sign like that would shear 1/2" dia bolts in the first year due to wind. Quote Link to comment Share on other sites More sharing options...
