Panduit PWBSPLEZ Wire Basket Bolted Splice

The Panduit PWBSPLEZ is a bolted splice kit engineered to join sections of wire basket cable tray while maintaining structural integrity and load capacity across the connection point. Fabricated from electro-zinc-plated steel, this splice provides corrosion resistance for indoor installations in mechanical rooms, above-ceiling pathways, and structured cabling environments where wire basket serves as the primary horizontal routing infrastructure. The bolted connection method delivers a rigid, vibration-resistant joint that meets the mechanical performance requirements of UL 2024 (Standard for Optical Fiber Cable Raceway) and NEMA VE 2 cable tray standards, ensuring that spliced sections perform as a continuous run under static and dynamic loading conditions.

Key Features

• Electro-zinc finish provides corrosion resistance for indoor structured cabling environments
• Bolted connection method ensures rigid, vibration-resistant joints across wire basket sections
• Steel construction maintains load capacity and mechanical integrity at splice points
• Designed for compatibility with Panduit wire basket cable tray systems
• Meets UL 2024 and NEMA VE 2 cable tray standards for mechanical performance

Wire basket cable tray installations require splices at every section junction, direction change preparation point, and field-cut termination where standard factory lengths don't align with architectural constraints. The PWBSPLEZ splice kit addresses the structural challenge inherent in these connections: transferring load across a discontinuous rail without introducing flex, sag, or rotational play that would compromise the tray's ability to support bundled copper, fiber, and coaxial cable over long horizontal spans. The bolted attachment method clamps the splice plate to both wire basket sections simultaneously, creating a lap joint that distributes tensile and shear forces across multiple fastener points rather than concentrating stress at a single weld or rivet. This design approach is critical in data center and enterprise network installations where cable fills approach or exceed 50% of the tray's cross-sectional area, generating sustained downward loads that would exploit any weakness in a poorly executed splice.

The electro-zinc coating applied to the steel substrate provides a sacrificial barrier against oxidation in climate-controlled indoor environments. While not intended for outdoor or high-humidity applications where hot-dip galvanized or stainless steel would be the appropriate material choice, the electro-zinc finish is sufficient for the majority of structured cabling deployments in office buildings, educational facilities, hospitals, and light industrial settings where ambient humidity remains below 70% RH and airborne contaminants are minimal. Installers working in above-ceiling spaces with minimal HVAC control—such as warehouse mezzanines or legacy buildings with uninsulated roof decks—should verify that condensation risk remains low before specifying electro-zinc hardware. For coastal installations or mechanical rooms with open-loop cooling towers, consult Panduit's material selection guide to determine whether an upgrade to hot-dip galvanized or Type 304 stainless steel splice hardware is warranted.

Installation requires standard hand tools (socket wrench or cordless impact driver with the appropriate hex or socket bit for the fasteners included in the kit) and takes approximately 3-5 minutes per splice once the wire basket sections are aligned and supported. The splice plates are positioned to span the joint on both the top and bottom rails of the wire basket, with fasteners inserted through pre-punched holes in both the splice plate and the basket wire. Proper installation procedure includes: (1) supporting both wire basket sections at the same elevation using temporary hangers or a ladder to prevent misalignment during fastening, (2) positioning the splice plates to achieve equal overlap on both sides of the joint, (3) inserting all fasteners finger-tight before final torquing to allow minor positional adjustments, and (4) torquing fasteners to the manufacturer's specified value—typically 15-20 ft-lbs for M6 or 1/4-inch hardware—to achieve uniform clamping force without crushing the wire basket profile. Under-torquing results in a loose joint that will shift under load; over-torquing deforms the wire and compromises the structural cross-section.

This splice kit ships as a single package containing the hardware required for one splice connection point. Large-scale wire basket installations—such as a 500-foot data center hot-aisle backbone or a multi-floor vertical riser system—will require multiple splice kits; calculate one splice per factory section length (typically 10 or 12 feet for standard Panduit wire basket) plus additional units for field cuts and future expansion joints. The silver electro-zinc finish provides a consistent visual appearance across the installation, matching Panduit's standard wire basket finish and maintaining a professional aesthetic in open-ceiling or exposed-infrastructure designs where the cable tray remains visible to building occupants.
