General Dimensions & Specifications

Fronek A/DE manufactures 7 models, each with 4 configurations. The different configurations are identified by the last digit in the snubber model number. This number identifies what attachment is fastened to the fixed end of the snubber and whether the snubber or dynamic restraint can be tested for operability while installed (testable vs. non-testable). Configuration designations -0 and -1 can optionally come with a transition tube kit and pipe, which effectively lengthens the overall assembly to provide the user with a simple way of accommodating dimensional limitations between the piping and building structure.

When ordering, specify the snubber model number, description, and stroke.
