Cable tray sealing units typically range from around $100 to several hundred dollars per unit, depending on type, size, and fire or environmental ratings.

Price Overview

The cost of cable tray sealing units varies widely based on material, design, and certification. For example, Roxtec CRST25 circular cable seals are priced at approximately $106 per unit and accommodate a single cable with a diameter range of 0.142″ to 0.472″, rated NEMA 4X / IP66 / IP67 for water and dust protection . Larger or multi-cable modular systems, such as FIRSTO firestop units or Dorn WSP weatherstops, are typically more expensive due to their fire-rated construction, modularity, and ability to handle multiple cables .

Factors Affecting Price

1. Material and Durability: Units made from galvanized or powder-coated steel frames with silicone or EPDM seals are more durable and weather-resistant, increasing cost .
2. Fire and Safety Ratings: Firestop-rated units (e.g., FIRSTO) or systems meeting IP66/IP67 standards command higher prices due to compliance with NEC, IEC, and local fire codes .
3. Modularity and Flexibility: Modular systems that allow easy addition or removal of cables reduce labor costs but may have higher upfront unit prices .
4. Size and Cable Capacity: Larger frames or units designed for multiple cables increase material usage and cost. Single-cable units are generally less expensive .
5. Installation and Lifecycle Costs: Some systems reduce labor by 20–30% due to ease of installation, which can offset higher unit prices over the project lifecycle .

Typical Price Range

• Single-cable, non-fire-rated units: $100–$150 per unit (e.g., Roxtec CRST25)
• Multi-cable, modular, fire-rated units: $200–$500+ per unit (e.g., FIRSTO or Dorn WSP systems)
• Custom or large-scale industrial solutions: Prices can exceed $1,000 per unit depending on specifications, environmental resistance, and compliance requirements .

Recommendations

When budgeting for cable tray sealing units, consider total installed cost, including labor, maintenance, and future expansion. Modular and flexible systems may have higher upfront costs but offer long-term savings and easier cable management . Always verify supplier lead times and minimum order quantities to align with project schedules.
