Selkirk 104406 Quick Grip Firestop Spacer Type-b Vent

Product Description

The SELKIRK 104406 is a Quick Grip firestop spacer designed for use with Type-B gas vent systems. It provides a secure, code-compliant through-floor or through-ceiling passage for vent pipe, maintaining proper clearance from combustible construction while supporting the vent run at floor or ceiling penetrations. The 104406 features an outside diameter of 4 inches and a plate footprint of 10 inches wide by 10 inches deep. Licensed HVAC technicians and gas-fitters install this component during new construction or vent system retrofits wherever a Type-B vent passes through a framed floor or ceiling assembly.

This firestop spacer is suited for residential and light commercial applications using Type-B double-wall gas vent pipe. It is installed at floor and ceiling penetrations to satisfy clearance-to-combustibles requirements specified in applicable mechanical and gas codes. The Quick Grip design simplifies field installation by allowing the spacer to be secured without specialty tools, making it a practical choice for vent system rough-in work on natural gas and propane appliances.
