The Spidex® curved jaw coupling brand and trademark are used exclusively by Lovejoy's wholly owned German sister company R+L Hydraulics. Meanwhile, in the North American market, Lovejoy markets the interchangeable product simply as CJ (Curved Jaw) couplings.
If you are looking to buy the product in the North American market (or a partner of the North American Lovejoy), you can learn more about the curved jaw coupling product by visiting the Lovejoy CJ product page and/or by downloading the Lovejoy CJ product catalog.
Furthermore, you can look up detailed part numbers and part number information on Lovejoy's Digital Parts Catalog (beta).
