High Deflection Shock & Vibration Isolation Mounts - 2K Series

Two stage shock mount and vibration isolator for severe dynamic environments such as shipboard and ground vehicles.


2K Series High Deflection Mount

Two stage shock mount and vibration isolator for severe dynamic environments such as shipboard and ground vehicles. Barry 2K-Series mounts offer the advantage of superior vibration and shock protection for a wide range of loads in a single compact unit. These isolators are ideal for isolating naval sonar equipment, ship board electronics and communications.
