Cost Considerations

• Quantity: Number of pillows or sealant tubes depends on tray dimensions and penetration size.
• Fire Rating: Higher F- or EI-ratings generally increase cost.
• Application Method: Caulking guns, trowels, or coatings may affect labor and material costs.
• Supplier and MOQ: Some suppliers offer bulk discounts; small orders may have higher per-unit costs.
• Project Environment: Indoor vs. outdoor, corrosive conditions, or high-traffic areas may require premium products. For accurate pricing, it is recommended to measure cable tray dimensions, determine the required fire rating, and request a quotation from suppliers such as 3M, AF Systems, Tengyu Chemical, or FLAMRO, as costs vary by region, quantity, and certification requirements .
