Metacaulk Pass Thru Pro

Quick Overview

Metacaulk Pass Thru Pro is a versatile firestop device that protects through-penetrations for up to 4 hours while allowing flexibility to add, re-add, or remove penetrants at any time. It reduces labor time with quick installation and flexibility to modify penetrants as needed. The intumescent material expands upon exposure to heat, forming a refractory char that tightly seals and prevents the spread of flame, smoke, and toxic fumes. This device will not mechanically pinch cables and is available in 2” (50mm) Round, 4” (102mm) Round, and 4” (102mm) Square variations (Single, Double, Tri-Plex, Six-Plex). With an excellent "L" rating, up to a 4-hour fire rating, and zero maintenance, Metacaulk Pass Thru Pro is UL Classified up to 4 hours and tested in accordance with UL 1479, ensuring reliable fire protection in various applications.
