The TMRB Series are track-mounted ring and bushing type isolators for use in architectural applications. The TMRB Series are designed to isolate only the floating (inside) walls used in two-wall isolation systems. These neoprene mounts are best used in applications where simple, cost-effective installations are necessary.    

Separating one wall from another via wall isolation systems significantly increases sound transmission losses. When noises entering through a wall disturb an adjacent space, the TMRB mounts are used to isolate the inner wall within a two-wall system. The walls can be made of concrete, block or drywall.   

The TMRB Series mounts support the inner, or floating, wall from the floor - providing isolation from vertical wall movements. The mountings are installed at the base of the floating wall studs and serve as permanent supports for the studs. The TMRB Series combine a steel bushing between two resilient, neoprene elements.
