Dewalt 9r189715 Upper Contact Arm

Product Description

The DEWALT 9r189715 is a replacement upper contact arm designed for use in DEWALT pneumatic nailers and fastening tools. The upper contact arm is a critical safety and actuation component that works in conjunction with the trigger mechanism to control nail firing. It must be depressed against the work surface before the tool will fire, preventing accidental discharge. This part is a direct OEM-style replacement intended for technicians and service professionals performing maintenance or repair on compatible DEWALT nailers.

The upper contact arm is typically replaced during routine tool servicing or after wear, damage, or breakage that prevents proper contact actuation. It is suited for use in professional construction, framing, finish carpentry, and general fastening applications where DEWALT pneumatic nailers are in service. Service technicians and tool repair shops are the primary installers of this component.
