Product Description
The Sealey AK3857 is a professional ratchet crimping tool designed for creating reliable electrical connections with both insulated and non-insulated terminals. Featuring interchangeable hardened and tempered jaws, this crimper offers versatility across a wide range of terminal sizes, making it an essential tool for electricians, automotive technicians and electrical contractors working with various cable specifications. Built with all-steel construction for long-term durability, the AK3857 incorporates large soft grip handles that reduce hand fatigue during extended use. The ratchet mechanism ensures consistent, uniform crimping pressure on every connection, eliminating the risk of under-crimped or damaged terminals that can lead to poor electrical contact or connection failure. The quick-change jaw system allows rapid switching between different terminal sizes without the need for separate tools. This crimper accommodates insulated terminals from 0.5-1mm² through to 4-6mm², and non-insulated terminals in 1.5, 2.5, 6 and 10mm² sizes. At 220mm in length, the tool provides excellent leverage whilst remaining compact enough for work in confined spaces such as control panels and junction boxes.
