Fasten the cable tray buttons

Cable tray buttons and fittings are fastened using bolts, nuts, clamps, or pre-mounted turn buckles, ensuring secure attachment to the tray and support structures.Step-by-Step Guide1. Identify the Type of Fastener Cable tray systems use different fasteners depending on the tray type and fitting:Truss-head bolts with combination nuts for standard screw-on fittings .Double clamps (DOP A2) for securing fittings to the tray rail .U-bolts for attaching trays to wall brackets or ST-series supports .Pre-mounted turn buckles for covers or bends . 2. Prepare the Tray and FittingsEnsure the tray sections are cut to the required length and deburred to remove sharp edges .Align the tray sections end-to-end or at bends, tees, or risers.For perforated trays, use the connector holes; for unperforated trays, drill holes as needed . 3. Fasten the Tray SectionsInsert the bolt through the fitting and tray holes.Place a washer if required, then thread the combination nut or hex nut on the underside .Tighten securely using a wrench or cordless drill with the appropriate socket . 4. Secure to Support StructuresFor wall-mounted trays, attach brackets using approved wall anchors and fasten the tray with U-bolts .For ceiling suspension, use threaded rods and trapeze hangers, securing the tray with nuts and washers . 5. Install Covers or Special FittingsCovers with pre-mounted turn buckles are placed over the tray and secured by closing the buckle .For bends or add-on tees, ensure the joint plates are aligned and fastened with bolts or screws as specified . 6. Safety and Quality ChecksWear protective gloves to avoid cuts from tray edges .Ensure all fasteners are tightened to prevent tray movement.Verify alignment and load distribution according to manufacturer specifications . By following these steps, cable tray buttons and fittings will be securely fastened, ensuring a safe and stable installation for electrical or IT cabling systems.
