|An afternoon last fall.|
The box is constructed from 2x2x1/8 aluminum angle. I purchased 100' in four 25' lengths from B&G Metals east of town. Strong, light, fairly non-corrosive, and easily cut with a hacksaw, the frame went together quickly. 3/8" SS bolts with washers and aircraft nuts hold it all together. Cross braces keep the whole thing rigid and square. 5/16" square U bolts clamp the frame back to the trailer. Its not going anywhere. A second set of lights increase the rig's visibility. At 6' width, it meets the beam of the truck and still has an inch or two to let UNA slip through on the inside. Some left over from fixing up fiberglass edges of another now protects varnished outwales from metal angles. All tolled, not bad for $150, eh?
|Looks distorted, but it is square!|
