Dewalt 142941 Lower Contact Arm

Product Description

The DEWALT 142941 is a lower contact arm replacement part designed for use in DEWALT power tools. The lower contact arm is a mechanical component that controls workpiece contact and trigger actuation in nailers and staplers, serving as a key safety and operational element that prevents fastener discharge unless the tool is pressed against a work surface. This part is installed by professional contractors and tool repair technicians performing component-level repairs on compatible DEWALT fastening tools.

The 142941 lower contact arm is suited for service and repair applications where the original contact arm has become worn, damaged, or lost. It fits into the nose assembly of the host tool and must be replaced to restore proper sequential or contact-trip firing operation. Repair shops and field technicians working with DEWALT pneumatic or cordless nailers and staplers are the primary installers of this component.
