800 Cable Tray Screw Specifications and Models

800 cable tray screws are available in steel and 316L stainless steel, designed for secure attachment of cable trays with options for self-drilling and screw-on systems.Material and FinishCable tray screws for 800 series systems are typically made from steel or 316L stainless steel, ensuring durability and corrosion resistance for both indoor and outdoor installations. Stainless steel screws are standard for stainless steel trays but can also be used on aluminum and steel systems as an option . Finishes are chosen based on environmental conditions and load requirements.Types of ScrewsSelf-Drilling Screws: These screws are designed to drill directly into the tray or supporting structure without pre-drilling, simplifying installation and reducing labor time. They are compatible with aluminum, steel, and stainless steel cable trays .Screw-On Systems: Used in traditional screw-on cable tray systems, these screws secure trays and fittings firmly. They are compatible with standardized fittings and allow for robust, heavy-load installations .SpecificationsRail Heights: Compatible with tray rail heights ranging from 4" to 7" .Connector Pairs: Splice plates and adjustable connectors typically include sufficient fasteners for standard installations; extras must be ordered separately .Bonding Requirements: Bonding jumpers are required for expansion splice plates, adjustable connectors, and tray discontinuities to maintain electrical continuity .Standards Compliance: Screws and cable trays conform to UL, NEMA VE 1-2017, ANSI/NFPA 70, and other relevant standards .Models and CompatibilityOBO Screw-On Cable Trays: These systems use standardized screws compatible with all OBO trays, designed for heavy loads and professional installation .Legrand Self-Drilling Screws: Available for aluminum, steel, and stainless steel trays, these screws are supplied with connector pairs for straight sections and fittings .Installation NotesEnsure screws are selected according to tray material and environmental conditions.For field cuts or additional spares, screws must be ordered separately.Follow bonding and grounding requirements to maintain safety and compliance. These specifications and models provide flexibility for various cable tray installations, ensuring secure, compliant, and efficient mounting of electrical systems.
