TMS Silent Clips-A24R are specialty brackets used in high-end construction to brace walls in a chase or double stud assembly creating an excellent acoustic environment by preventing sound from travelling from one room to another.  Engineered for maximum effectiveness, heavy-duty brackets are combined with a patented thermoplastic rubber in a sound cell design which aids in breaking up and absorbing sound.

A24R Clips are used to brace walls in a chase or double stud construction strengthening the wall apparatus, as each part of the wall supports the other.  It is a low-tech solution for advanced acoustic and thermal isolation.  Introducing air space between walls is particularly helpful for low-frequency sound reduction as well as convenient in areas where extra space between walls is required for plumbing, ducts or electrical wiring.  When combined with proper covering material, they have a high fire-resistance rating.  A24R clips were developed to meet requirements of attachment, sound control and fire resistance.  

A24R Brackets simple design makes installation easy and uncomplicated, reducing time and cost.  It is provided with several fastening holes and can gap walls with a minimum of 1" to maximum 7" gap between walls.  Can be used on wood using #8 Coarse Threads or on steel using Self Tapping Type S Screws. 


  • Fully engineered component designed to improve wall strength and increase wall of a chase wall installed in an acoustically sensitive environment.
  • Designed as a heavy-duty bracket which is specially designed to help absorb vibration and minimize structure-borne noise.
  • Incorporates a thermoplastic rubber mount with a sound cell design to absorb noise.
  • Wall height can be increased in acoustic chase wall applications, eliminating the need for extensive bracing and oversized steel members.
  • Simple design makes it adaptable to hundreds of applications
  • Does not use metal washer or metal insert in rubber to meet fire-safety specifications
  • Provided with several fastening holes including 3/16" slotted holes in bracket fixing surface
  • Supplied as fully assembled component - no site assembly required.

Installation Guide

Installation Notes

  • Minimum gap between walls is 2".  Smaller gap down to 1" can be achieved by fixing the bracket on a diagonal plane between the two walls.  When mounting the bracket diagonally, extreme care must be taken to ensure the bracket's fastening surface does not come into contact with the studs on the opposing wall. 
  • Maximum gap between walls is 7".  Greater distances can be achieved by extending the bracket length using a piece of stud.  In such instances, please contact our engineers to confirm engineering specifications.
  • A24R to be fastened to structure with a minimum #8 screw or masonry sleeve anchors (see fasteners manufacturers specifications). Nails may not be used!
  • When installing, ensure that no part of the two opposing structurers are touching or has the potential to compromise the acoustical isolation of the two separate structures.
  • Load ratings to be confirmed with manufacturers specifications, based on project environment.


Step 1- Fasten Brackets To Wall Assembly

Secure first wall assembly in place prior to installing the A24R brackets.

Measure for placement of A24R sound isolation brackets on the wall studs (steel or wood).

A24 brackets should be spaced 24" apart.

Fasten the brackets to the studs using appropriate fasteners

     -Wood: #8 x 2-1/2" Coarse Threads

     -Steel: #8, #10 or #12 x 1-5/8" Self Tapping Type S


Step 2 - Fasten Brackets to 2nd Wall Assembly

Raise the 2nd wall assembly into place so that there is a maximum 7" gap between the wall assemblies.

Fasten the bracket to the second wall assembly.  Use appropriate fasteners for the building structure material. 

Step 3 - Install The Drywall

Fill the gap between the wall assemblies with sound rated insulation.  Raise the drywall into place and fasten to the appropriate wall assembly with standard drywall screws.

Step 4 - Seal The Perimeter

Use acoustical sealant to fill the gaps around the perimeter of the wall and use putty pads around any electrical outlets.

Bolts too short to engage nylock nuts!

Comments about Resilmount A24R Double Clip For Acoustical Bridging:
For a product at this price I was very surprised that (1) bolts are too short to fully engage the nylock nuts and therefore liable to come apart at some point inside an enclosed wall assembly (2) red rubber is not as resilient as black rubber used in other resilent clips and brackets.
