Crimping pliers for wire end ferrules feature compound leverage, a ratchet mechanism, and adjustable locking with pressure point release. These pliers come with interchangeable crimping profile inserts, which are fixed by a catch holder in the tool body, allowing for quick profile changes without the need for additional tools. Two extra crimping profiles are stored in the integral magazine holders on the legs of the pliers. The tool body is constructed from strong, specially tempered, hardened sheet steel, designed for reduced manual force through leverage transfer. It includes an adjustable ratchet mechanism with automatic release to ensure standard-compliant crimping pressure, and ergonomic 2-component handle sleeves. The pliers are fully equipped with hardened precision crimping profile inserts and weigh only 690 g, including three crimping profile inserts.
