This unique design is mainly used in repairs and maintenance of refrigeration systems, where often times the nuts or couplings are made from soft materials, thus the importance of having a perfect fit, to avoid damaging the parts
They help tighten or loosen pipe joints made mainly with soft metals, like bronze, copper and aluminium
They have an ergonomic geometry that improves grip and fastening since their openings are precision-cut
Combination wrenches feature two same-size openings; the open-end allows you to quickly apply low torque and the box-end allows you to apply final and greater torque
The opening angle allows two actionable positions, reducing the recovery angle to 15°
Box-end: 30° recovery angle
Open-end: 15° recovery angle
The openings are machined to precision for a perfect fit with nuts and bolts
