The Kukko 2-Arm Quick Adjusting Universal Pullers, from Anglo American Tools, offer "Glide and Fix Technology," meaning the geometry of the cross-bar and sliding parts has been optimized to ensure particularly easy movement of the extractor hooks along the cross-bar. This also ensures a rock-solid hold once positioned on the bolts. A manual adjustment knurl allows rapid loosening and adjusting of the extractor hooks without using a wrench. With self-lock technology, by turning the locking screw the hooks are centered and tensioned and therefore firmly grip the piece to be pulled off. This prevents the hooks moving or slipping off.
