The A237, A237R, A237BR, and A237CR Resilmount clips are designed for different furring channel and framing connections. The A237 is a direct-fix option, the A237R supports resilient metal furring channel connections, the A237BR is designed for bar joists, and the A237CR connects CRC channels to furring channels. Choosing the right clip for the framing system helps contractors maintain acoustic separation.
All four options are available through Buildcorp Direct, making it easier to source the appropriate sound isolation clip for commercial construction projects.
Why Does Choosing the Right Sound Isolation Clip Matter?
Sound isolation is an important consideration in commercial and residential construction. Whether building offices, apartments, hotels, or healthcare facilities, contractors need to consider how sound travels through the walls and ceilings.
One common problem is structure-borne sound. Vibrations travel through framing members and other rigid connections, allowing noise to pass between spaces.
Resilient sound isolation clips help address this problem by reducing direct vibration transfer between the supporting structure and the finished wall or ceiling assembly. However, not every clip is designed for the same connection.
The Resilmount A237 range available through Buildcorp Direct includes different configurations for direct fixing, metal furring channels, bar joists, and CRC channel systems.
Selecting the wrong clip can create installation difficulties, compromise the intended assembly, or require additional materials and labor to correct.
Choosing the correct sound isolation clip helps maintain the intended acoustic separation while ensuring compatibility with the framing system.
What Is the Difference Between the A237, A237R, A237BR, and A237CR?
Although these four products belong to the Resilmount A237 family, their primary difference is the framing connection they are designed to accommodate.
| Product | Primary Application | Best Suited For |
|---|---|---|
| A237 | Direct-fix furring channel sound clip | Assemblies requiring direct fixing |
| A237R | Metal furring channel resilient clip | Specified resilient metal furring channel assemblies |
| A237BR | Bar joist to furring channel connection | Steel bar joist framing |
| A237CR | CRC channel to furring channel connection | CRC-supported ceiling assemblies |
Contractors should select the clip based on the specified framing configuration as the four models aren't interchangeable.
Each A237 clip is intended for a different framing connection. The supporting structure is the starting point for selecting the appropriate model.
When Should You Choose the Resilmount A237 Direct-Fix Clip?
The Resilmount A237 Furring Channel Mount is the foundational model in the A237 range.
It provides a straightforward way to decouple gypsum board from supporting wall or ceiling framing. This helps limit vibration transfer through the finished assembly.
Unlike the A237R, the standard A237 doesn't include the additional thermoplastic rubber isolation element.
The A237 offers:
- Compatibility with 7/8-inch and 1-1/2-inch furring channels
- A ¼-inch mounting hole for compatible fasteners
- A maximum dead load of 55 pounds per clip
- Compatibility with multiple wall and ceiling assembly configurations
- A simple design suited to several direct-fix applications
The A237 is particularly useful when contractors need a direct-mounted furring channel clip, and the specified acoustic assembly doesn't require the additional rubber isolation component.
The A237 is suited to direct-fix applications where a straightforward resilient furring channel connection meets the project specifications.
What Makes the Resilmount A237R Different From the A237?
The Resilmount A237R Resilient Sound Isolation Clip for Drywall builds on the original A237 design by incorporating a thermoplastic rubber isolation element.
This additional component helps absorb vibrations and reduce their transfer through the supporting structure.
The A237R is compatible with several common substrates, including:
- Wood framing
- Steel framing
- Concrete
- Concrete masonry units (CMU)
Like the A237, the A237R accommodates 7/8-inch and 1-1/2-inch furring channels. It is also suitable for specified fire-rated wall and ceiling assemblies. Contractors must confirm the applicable tested assembly and required installation components.
Is the A237R Better for Acoustic Performance?
The A237R is designed to provide additional vibration isolation through its rubber element. This makes it particularly relevant for projects with demanding acoustic requirements, including multifamily housing, hotels, offices, and other spaces where noise transmission needs careful management.
However, the clip alone doesn't determine the finished wall or ceiling's Sound Transmission Class (STC). Acoustic performance depends on the entire assembly, including framing, gypsum board layers, insulation, fastener placement, and installation quality.
Contractors can explore the Resilmount A237R through Buildcorp Direct when a specified system calls for additional vibration isolation.
The A237R adds a thermoplastic rubber isolation element, making it suitable for assemblies requiring greater control of vibration transfer.
When Is the Resilmount A237BR the Right Choice?
Steel bar joists are commonly used to support floors and roofs in commercial construction.
When contractors need to install a suspended acoustic ceiling beneath these members, the connection requires a suitable mounting system.
The Resilmount A237BR Bar Joist to Furring Channel Resilient Clip is designed for this specific application.
The A237BR uses a bolt connection that passes through the steel joist and resilient mounting component. The lower portion accepts a standard furring channel helping acoustically separate the gypsum board ceiling from the framing above.
Features:
- Designed for steel bar joist applications
- Suitable for new or existing dropped ceiling systems
- Accommodates standard furring channels
- Supports acoustic separation between ceiling and floor assemblies
- Available with different bolt lengths, including 3, 4, and 5 inches
Why Does Bar Joist Compatibility Matter?
A standard direct-fix clip may not provide the correct connection for a steel bar joist assembly.
Using the A237BR allows contractors to work with a purpose-designed connection rather than adapting an unsuitable bracket. This is particularly useful for commercial projects with exposed structural steel or suspended ceilings beneath open-web steel joists.
The A237BR is designed for bar joist applications where a suspended gypsum board ceiling requires acoustic separation from the structure above.
When Should You Use the Resilmount A237CR?
Some suspended ceiling systems use cold-rolled channel (CRC) as part of their supporting framework. These systems require a clip that connects the CRC support to the furring channel while maintaining acoustic isolation.
The A237CR Resilmount CRC Furring Channel Resilient Clip is specifically designed for this connection.
The A237CR combines an A237R-style resilient clip with a metal bracket that attaches to the CRC. The upper bracket fits over the cold-rolled channel and locks into place. The lower portion accepts standard 7/8-inch or 1-1/2-inch furring channels.
This arrangement helps decouple the finished gypsum board ceiling from the supporting CRC framework.
How Is the A237CR Different From the A237BR?
Both clips are designed for specialized suspended ceiling connections, but they attach to different supporting members.
The A237BR is intended for steel bar joists, while the A237CR connects to cold-rolled channels.
For contractors working with CRC-supported ceiling assemblies, the A237CR available from Buildcorp Direct provides a purpose-designed solution.
The A237CR connects CRC to furring channels while maintaining the acoustic separation required by the specified ceiling system.
Which Resilmount A237 Clip Should You Choose?
The right Resilmount clip depends on how the furring channel connects to the supporting structure.
The A237 offers a foundational direct-fix solution. The A237R adds a thermoplastic rubber isolation element for greater vibration control. The A237BR accommodates steel bar joist connections, while the A237CR is designed for cold-rolled channel-supported assemblies.
Each product serves a different purpose, and the best option is the one that matches the project's specified framing and acoustic system.
