Price of seismic bolts for cable trays

Seismic bolts for cable trays typically range from $2 to $10 per bolt, depending on size, grade, and manufacturer.

Overview

Seismic bolts are used to secure cable trays to structural supports in compliance with seismic bracing standards. They are often paired with threaded rods, universal restraint clips (URC), and other hardware to form a complete seismic bracing system for cable trays. Common bolt sizes include 3/8” and 1/2” diameter, designed to meet minimum breaking strengths required for seismic loads.

These bolts are usually high-strength, zinc-coated steel to resist corrosion and maintain structural integrity during seismic events.

Typical Pricing

Small bolts (3/8” diameter, standard grade): $2–$4 per boltMedium bolts (1/2” diameter, high-strength grade): $4–$7 per boltSpecialty seismic bolts or pre-assembled kits: $7–$10 per bolt equivalent Prices vary depending on quantity purchased, supplier, and whether the bolts are part of a pre-packaged seismic bracing kit. For example, seismic bracing kits from Legrand/Cablofil include bolts, clips, and wire rope assemblies, which can increase the per-bolt cost but simplify installation.

Purchasing Considerations

Compliance: Ensure bolts meet UL listing, ASCE, and local building code requirements for seismic applications. Compatibility: Match bolt size to threaded rods, cable tray type, and URC clips for proper load distribution. Supplier Options: Major suppliers include Eaton (B-Line/TOLCO), Legrand/Cablofil, and Unistrut, which offer both individual bolts and complete seismic bracing kits.

Bulk Orders: Buying in bulk often reduces the per-bolt cost and ensures consistent quality for large installations. For exact pricing, it is recommended to contact suppliers directly or request a quote for the specific bolt size, grade, and quantity required for your project.
