The crimping pliers for wire end sleeves feature a compound lever mechanism, a ratchet mechanism, and an adjustable locking system with a pressure point release. This tool comes with interchangeable crimp profile inserts that are secured by a catch holder in the pliers body, allowing for quick profile changes without additional tools. Two extra crimp profiles are housed in the integrated magazine holders on the legs of the pliers. The pliers body is made of strong, specially hardened sheet steel, designed for reduced manual force transfer through leverage. It includes an adjustable ratchet mechanism with automatic release to ensure compliance with crimping pressure standards, as well as ergonomic two-component grip sleeves. The pliers are fully equipped with hardened precision crimp profile inserts and weigh only 690 g, including three crimp profile inserts.
