The chrome plating gives the Cobra 87 03 250 particularly good rust protection. The handles are coated with non-slip plastic.For pipes, nuts, sleeves, for various kinds of components: the professional user applies the Knipex Cobra quickly and accurately with just one hand movement. The spring-loaded hinge bolt locks securely into place without adjusting inadvertently. Thanks to the 25-fold fine adjustment, the Cobra can be ideally adjusted to different sizes of the component. This fine adjustment also makes sure that the distance to the handles remains hand-friendly for every grip width.Tough and strong:The Knipex Cobra is further stabilised by the box joint design. Unlike pliers with mounted joints, no tilting forces arise when under strain. The handles stabilise each other in the joint.Self-locking mechanism ensures a high degree of efficiency:The Knipex Cobra clamps onto the component securely by itself thanks to the jaw geometry developed by Knipex. This means the user can put all energy into the desired movement without pressing the pliers handle together – and thus without energy loss: round components can be turned, bolted connections tightened and released.Brief overview:• Modern high performance water pump pliers• 25-fold fine adjustment at the touch of a button for fast adjustment to different sizes of component• Self-locking on pipes and nuts• Large grip width (up to a wrench opening of 46 mm / pipes up to 2 inches) with low weight (335 g)• Gripping teeth hardened to approx. 61 HRC using high frequency for a secure grip and a long service life• Grips flat, round and angled components• High level of user comfort due to constant hand-friendly gripping position resulting from fine adjustment• Handles coated with non-slip plastic• Chrome vanadium electric steel, forged, oil hardened• Chrome-plated for the best rust protection
