Overall the correct size and shape and attaching part is correct and we'll attached. The height adjusting bracket is not full length as on the Heng's lid. Instead, it is a short metal piece attached to a rib of plastic moulded into the inside dome part of the lid. Because these lids all succumb to the effects of the sun, it is unknown if the rib of plastic holding the bracket will outlast the useful life or be the determining factor in the useful service of this lid. For now, I am pleased with the ease of installation, the fit and overall appearance. I would buy these again.
