Product Description

NELSON AA-479 PILLOW FIRESTOP TYPE II pack of 10 NEW AA0479 9.6 x 8 x 3 10/Ctn. Product Description Nelson Firestop Pillow (PLW) is a compressible firestop device that is well suited for installations where frequent changes may be required. PLW consists of a mineral fiber treated with a highly intumescent material enclosed in a strong polyethylene bag. When exposed to fire, the pillows expand to lock the seal in place. Even though PLW is classified as a permanent firestop system for several applications including steel and aluminum cable trays, PLW also is an excellent temporary seal. .. Application Nelson Firestop Pillow (PLW) is ideally suited for applications for cable tray penetrations or temporary closures requiring fire rating integrity. Install Nelson PLW into areas where the surfaces are clean and free of dust, grease, oil, loose materials, rust or other substances. Pillows may be coated with cable pulling lubricant for ease of installation. Tightly pack the pillows and insert lengthwise into openings. Actual installation should be in accordance with the appropriate Nelson application system drawing. .. Availability AA0478 9.6 x 4 x 3 20/Ctn. AA0479 9.6 x 8 x 3 10/Ctn.
