Resilmount A237
The Resilmount A237 is a rigid, zinc-coated direct-fix bracket that secures 7/8" or 1 1/2" furring channel to wood or light-gauge steel framing. Ideal for straight, code-friendly wall and ceiling assemblies where full resilient isolation isn't required — a budget-smart way to keep channel spacing consistent and finishes uniform.
- Reliable Channel Support: Direct-fix bracket secures 7/8" or 1 1/2" furring channel to wood or light-gauge steel — walls and ceilings stay straight, stable, and predictable.
- Compact & Easy Installation: Low-profile form with convenient screw locations speeds attachment and fits tight build-ups and retrofits for clean, repeatable layouts.
- Code-Friendly & Durable: Rigid, zinc-coated steel resists creep and corrosion; integrates cleanly into rated assemblies when detailed per listing and project engineering.
- Budget-Smart Framing: Cost-effective hardware that minimizes shimming, trims labor, and maintains consistent channel spacing for professional finishes.

Adds MLV over Good for a denser limp-mass layer.
Estimated STC — Planning use only
This value is an approximate assembly projection, not a project-specific assessment, certified laboratory test result or performance guarantee. Actual performance varies with the complete assembly, installation, flanking paths, penetrations and site conditions.
Estimates follow the manufacturer's standard clip and hat-channel layout for walls and ceilings. A 10% coverage buffer is recommended to cover cuts and re-work.

- STC 30-39: Loud speech clearly audible next room.
- STC 40-49: Loud speech muffled — normal residential wall.
- STC 50-59: Loud speech barely audible; suitable for offices & multi-family.
- STC 60+: Approaches studio-grade isolation.
