2.5SRMT-9-350 Spring Isolator/Restrainer

SRMT/F series are heavy-duty seismic restrained mounts with unique sliding channels designed to withstand lateral loads in combination with vertical loads up to 18,450 lbs.


Seismic Restrained Spring Isolators are used for a variety of industrial and mechanical equipment where isolation of the lower frequencies is critical.

There are two available configurations:

  • SRMF: flat top with an inside leveling adjustment feature 
  • SRMT: bolted top with leveling adjustment feature 


Recommended for vibration isolation for:

HVAC equipment, fan air circulation systems, compressors, pumps, chillers, AC units, cooling towers, inertia bases, etc.

Safety factor - Springs will accomodate 50% extra load from rated load to solid load.
All mounts' elements are safe at solid load.
Interlocking steel channels restrict the movements (snubbers) in all horizontal directions
Rubber lining inside bottom metal channels prevents metal-to-metal contact.
Anti-skid rubber acoustical pad.
Zinc plates housings and springs provide good corrosion resistance.
Elastomer spring base cap provides better vibration isolation, load distribution, and noise reduction.
Springs are colour coded and easily replaceable
Recommended load range: from 50% of rated load to rated load.
Rugged welded steel housing designed to withstand seismic and high wind forces.
