Fits and performs as designed on my 4" X 48" forks. Mine had Vevor stickers on it. Like that they beveled in the lock bars to match up to the interior width of extension. Good looking welds on the lock bars. Made in China if that matters to anyone.
I got what I was looking for.... Good quality and the price is so cheap that I had to make sure whether it was for a single piece or pair... $99 for a sturdy forklift extension pair with free shipping is a total win win....
