Product Description
The Simpson FSS Furring Stabilizer Strap is a straight, field-bendable strap engineered to create a precise 1" separation between furring channel and joist, making it the go-to solution for installations that incorporate Thermafiber insulation systems. Manufactured by Simpson, this furring channel stabilizer is built to support both sound control and fire-rated ceiling assemblies, giving contractors a reliable, code-conscious fastening option for commercial and residential joist applications.
Key Features
- Creates a consistent 1" furring channel-to-joist separation - ensures proper Thermafiber insulation integration without guesswork or custom shimming on the job site
- Secures furring channel to all joists - delivers uniform structural support across the entire ceiling assembly, reducing the risk of inconsistent attachment points
- Field-bent straight strap design - can be shaped on site as needed per application, giving installers the flexibility to adapt to varying framing conditions without ordering specialty pre-formed parts
- Supports an efficient sound barrier and a one-hour UL-listed fire rating - helps the overall assembly meet acoustic and fire performance requirements when installed per specifications
- Installs with standard fasteners - fastened to channel with a #8 self-tapping steel screw, then twisted 90 deg. and secured to the joist bottom flange, keeping the installation process straightforward and tool-friendly
- 22-gauge zinc galvanized construction with a G90 coating - provides corrosion resistance suited for interior ceiling framing environments where long-term durability matters
Why This Product
- Designed specifically for Thermafiber insulation systems - the 1" standoff this strap creates is purpose-built to accommodate Thermafiber integration, so the assembly performs as intended without improvised workarounds
- Supports fire and sound performance in a single component - by enabling a one-hour UL-listed fire rating and an efficient sound barrier, this strap contributes to two critical building performance goals at once, simplifying the specification process
- Field-adjustable without sacrificing consistency - the straight strap can be bent on site to suit the exact conditions of each joist bay, reducing material waste and keeping installation moving efficiently
- Backed by Simpson engineering and domestic production - a trusted name in structural connectors and fastening hardware, Simpson delivers the quality control and technical documentation that contractors and inspectors rely on
