The Alden HVAC Wrench is an open-end ratchet that needs only 30 degrees swing angle, thereby eliminating the need to remove and reposition the wrench with each turn, the manufacturer states. It has a small head size and an interactive grip that increases as more torque is applied, making it useful for fasteners that have tight clearances. Made of stainless steel, this ratchet is best for use with fasteners along hydraulic, pneumatic, and cable lines, says the company.
