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.
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 Gauge
Compare how the A237 performs across assembly tiers. Select an assembly below to see the resulting STC score.
A237 + hat channel + MLV + double 5/8" drywall with Green Glue between layers, insulated stud wall.
- 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.
