Crimping Tools for Working at Height Here at Secure Tools, we stock a selection of handheld crimping tools designed for working at height safely. Compact and easy to transport anywhere you go, these plier-like tools are used to join components together, such as metal objects, by pressing together to produce a crimp or seal. Expertly made from high-quality steel, our range of corrosion-resistant crimping tools deliver exceptional performance in all working conditions. And the ergonomic handle designs provide a comfortable, super-strong grip you can rely on. And to make working at height safer for everyone, each crimping tool in the range includes a sturdy, stainless steel attachment ring that lets you tether it to a harness and prevent tool droppages.
