Dewalt n587377 Contact Trip

Product Description

The DEWALT n587377 is a replacement contact trip designed for use in DEWALT pneumatic nailers and fastening tools. The contact trip is the nose-mounted safety mechanism that must be depressed against the work surface before the tool can fire a fastener. This part controls the sequential or bump-fire operation of the nailer and is a wear item subject to repeated impact and abrasion during normal use. Licensed contractors, carpenters, and finish trades technicians replace this component when the original shows wear, damage, or prevents the tool from cycling correctly.

The n587377 contact trip is suited for repair and maintenance of DEWALT pneumatic nailers used in residential and commercial construction applications. Typical install scenarios include jobsite tool repair when the contact trip no longer depresses smoothly, fails to actuate the firing valve, or is visibly cracked or bent from contact with hard substrates such as concrete board, hardwood, or engineered lumber.

Key Features

• OEM replacement contact trip sourced directly from DEWALT parts
• Restores proper sequential or bump-fire actuation when worn original fails
• Designed to fit the original mounting geometry without modification
• Wear-rated component built for repeated contact with work surfaces

Compatibility

Designed as an OEM-style replacement contact trip for compatible DEWALT pneumatic nailers. Refer to your tool model number and DEWALT parts diagram to confirm fitment before installation.

Installation Notes

Contact trip replacement should be performed by a qualified service technician familiar with pneumatic fastening tools. Disconnect the air supply and depressurize the tool completely before disassembly. Consult the tool service manual for fastener torque sequence and proper reassembly order. Do not operate the tool without the contact trip fully seated and secured, as this safety mechanism prevents unintended firing.
