Square u-bolts have slightly rounded corners. U-bolts, when properly torqued will typically conform if close to the shape of the item it is fitting over. Please, if you have any questions, call before ordering.
Please note that the “L” measurement (length) may be slightly longer and is not exact depending on total rod length. The reason the “L” measurement may be longer, we add “C” and “L x 2” measurements to get the total material length which is made in even lengths, 22, 28, 38 etc.
