I consulted and closed the question without grading. A literal translation was not appropriate here, and I am aware that the lack of context made it nearly impossible to find the correct term. With all due respect, this was most certainly not based on guesswork :)

I am sorry but "placa de apoio" definitely IS NOT the translation of what is written in English. Nor could it have been assumed from the illustration/text submitted. Guess work is not the best solution for otherwise untranslatable terms.

After consulting with the client, I translated it simply as "barra de apoio" or "barra de suporte" if memory serves. I could find no mentions of "placa cinco" to describe anything other than license plates, and I felt "barra V" was not appropriate as the structure is not V-shaped.

I was not pleased at closing this without grading--I never am, as you cannot leave a comment (can you?). In retrospect, I should have taken the time to thank you all in a discussion entry.

Would you be so kind as to inform those who took their time to provide you with suggestions as to what was the "Answer found elsewhere" ??
