The RB series of stabilisers is composed of models (RB F1-F6) for fitting to the side of the machine with adjustment from below and models (RB S1-S3) for fitting below the machine and again having adjusment from below.
The entire series is very adapt for specific applications in damp environments or outside in that the screw and pivot foot are protected from above by the closed housing and nylon cover. Unlike the RT and RA series the RB models do not allow for the screw being removed from above for maintainence and therefore careful thought needs to be given for heavy machinery with particular consideration of the models that are fitted to the machine sides as these can be removed without having to lift the machinery the length of the trapezoidal screw.
