Overview

The nVent Quick Tray Pro Splice Washer (SKU: QTPSSW3BLK) is a precision-engineered, black steel washer designed to deliver superior mechanical stability and corrosion resistance in cable management systems. Engineered for compatibility with nVent’s Quick Tray Pro Splice Kits (QTPBNWKBLK for black finish or QTPBNWK for zinc finish), this splice washer ensures reliable bolted connections for turns, bends, tees, and tray-to-tray splices. Measuring 4.00 x 4.00 x 8.00 inches (102 x 102 x 203 mm), the washer provides a robust bearing surface for splice bars and hardware, distributing load evenly to prevent deformation or loosening under dynamic loads or vibration—critical in industrial environments where cable trays must maintain structural integrity over time. Industrial professionals rely on nVent’s Quick Tray Pro system for its modularity and ease of installation, and the QTPSSW3BLK plays a pivotal role in this ecosystem. Unlike generic washers, these splice washers are manufactured from high-strength steel with a durable black finish that resists chipping and fading, ensuring long-term performance in harsh conditions. They are ideal for use in commercial buildings, data centers, manufacturing plants, and utility installations where cable trays must accommodate complex routing while maintaining compliance with NEC and other electrical codes. The versatility of the QTPSSW3BLK extends beyond simple tray-to-tray connections. When paired with nVent’s Quick Tray Pro Splice Bars (such as the QTPUS10BLK), these washers enable secure fastening in tight spaces, elbows, and junctions—areas where traditional hardware often fails. The black finish not only enhances corrosion resistance but also aligns with modern aesthetic requirements in exposed installations. Each package contains 50 washers, providing ample supply for large-scale projects or inventory stocking. Installation is straightforward: professionals align the washer with the splice kit’s bolt pattern, ensuring proper engagement with the tray wall and splice bar. The 8-inch length provides ample surface area for load distribution, reducing the risk of pull-through or misalignment. For projects requiring custom lengths, nVent’s splice bars can be cut to fit using standard bolt cutters, further enhancing flexibility. The system’s modular design allows for rapid reconfiguration, making it a preferred choice for facilities undergoing upgrades or expansions. nVent, a global leader in electrical and thermal management solutions, brings decades of expertise to the Quick Tray Pro line. Known for innovation and reliability, nVent’s products are trusted by engineers and contractors worldwide to meet the demands of modern electrical infrastructure. The QTPSSW3BLK splice washer exemplifies this commitment, offering a combination of durability, precision, and ease of use that reduces installation time and maintenance costs. Whether used in new construction or retrofit applications, this washer ensures that cable tray systems remain secure, organized, and compliant—delivering peace of mind in critical infrastructure.

How to Connect QUICK TRAY PRO Cable Tray Sections Using QTPSSW3BLK Splice Washers

This guide outlines the procedure for securely joining QUICK TRAY PRO cable tray sections, including bends and tees, by utilizing QTPSSW3BLK splice washers and compatible splice kits.

Estimated time: 20m

Tools needed:

Hoffman Side Action Bolt Cutter, Wrench

Supplies needed:

QTPSSW3BLK Splice Washers, QTPBNWKBLK Splice Kits, QUICK TRAY PRO Cable Tray sections

  1. Prepare Tray Sections

    If forming a bend, tee, or custom length, cut the QUICK TRAY PRO cable tray sections to the required dimensions and angles using the Hoffman side action bolt cutter. Ensure cuts are clean and minimize sharp edges that could snag wires.

  2. Align Tray Sections

    Position the cable tray sections to be connected, ensuring they are properly aligned for the desired configuration (e.g., straight run, 90-degree bend, tee connection). Refer to specific assembly diagrams in the manual for precise alignment.

  3. Insert Splice Kit Hardware

    Place the bolt from the QTPBNWKBLK Splice Kit through the designated holes in the cable tray sections, ensuring proper engagement with all layers of the tray or splice bar.

  4. Secure with Splice Washer and Nut

    On the opposite side of the bolt, place the QTPSSW3BLK Splice Washer over the bolt, ensuring it covers the connection point as indicated in the specific assembly diagram. Then, thread and tighten the nut from the splice kit onto the bolt using a wrench until the connection is secure and stable. Repeat this process for all required fastening points.
