Steel cable trunking is a common service penetration found on site, typically 50, 100, or 150mm. However, we now have test data for cable trunking as large as 300mm wide x 150mm high when using Quelfire Fire Pillows to firestop the cables, double or pattress-fit QuelStop Fire Batt, and a QuelStop Batt box detail, 300mm both sides.
