Ideal for round or irregular shaped bundles, push-type seals are used with a push-type tensioner to secure steel strapping. The flanges on a push-type seal completely overlap so both strap ends must be manually pre-threaded through the push seal before tensioning. These seals are usually crowned to prevent them from migrating too far into the hand tool during tensioning. A reverse notch joint is typically used to secure push-type seals.
