Double-clevis fittings of types U2 and U2K are designed to connect the pin of a suspension insulator or shackle to other line fittings. The U2K modification (shortened clevis) is used in insulating suspensions and guy wire attachments without protective fittings, allowing for a reduction in the length and weight of the suspension. The products are manufactured in accordance with TU 3449-001-52819896-2010.
