DYNAMAX & DYNAMAX PLUS Suspension Systems

Provide an attachment platform for cable trays, equipment partitions, and hot and cold containment barriers from the structure to below the ceiling plane while eliminating penetrations through the ceiling.


Key Selection Attributes DYNAMAX
Structural Grid
Structural Grid
Easy integration into a conventional grid system using AXTBC clip and DYNAMAX boss channels
Supports up to a 1,200 lb. point load rating using 3/8" -16 threaded rod at 48" x 48" connection points
Suspension system has continuous threaded boss channel, allowing 3/8"-16 threaded rod to be installed to the suspension system at any location
Available in 24" x 24", 24" x 48", and 48" x 48" suspension system layouts 
Fully accessible system allows for future expansion and upgrade
Non-progressive installation gives the ability to remove or replace a section of the system without the need to dismantle those components around it
Cross tees not bearing any load are removable for plenum access without compromising the structural integrity of the system
Factory gasketing available upon request.
10-Year Limited Suspension System Warranty; 30-Year Limited Ceiling System Warranty
Allows for longer spans (6' and 8') while also providing greater load-carrying capacity  
6' spacing allows for direct attachment to steel joists or pre-cast concrete tees   
Eliminate 1/3 or 1/2 of threaded rods/accessories utilized today for typical 48" hanging spans  
Supports point loads of up to 1,090 lbs. at the mid-point of 4' spans (up to 1,800 lbs. for static point loads)
