Abstract: A shock and vibration isolator comprising a housing securable to the support structure and having a rigid base, top and side portion, a traveler in the housing orientated about a longitudinal axis and configured to move axially and radially relative to the base portion of the housing, the traveler having a connection portion attachable to the payload and a radially-extending transfer portion, an upper, lower and radial non-rigid compliant element disposed axially between the top portion of the housing and the transfer portion of the rigid traveler, disposed axially between the base portion of the housing and the transfer portion of the traveler, and disposed radially between the side portion of the housing and the traveler, respectively, the non-rigid compliant elements operatively configured and arranged to selectively decouple axial and radial motion of the payload from axial and radial motion of the support structure.
