Manual crimper for 20 mm crimp caps. The product design features tough, light glass-filled plastic body with curved handles which improve hand comfort during use compared to metal grip designs. The bottom-pull handle allows for a steadier hold than top-push handles. An easily-viewed adjustment knob is located at the head of the tool. The clearly shown + and - symbols along with the directional arrows, simplify adjusting the intensity needed. The knob is also designed to indicate when the crimp setting has been reached, when it fully contacts the body of tool.
