BR Series Mounting Bridles secure round base components such as UTR, URM, and PO Series stages and SL, SK, and VGM Series mirror mounts to similar size linear and rotary positioning devices such as UMR, MVN and TGN Series stages. Much like motor clamps, precision machined tabs on the steel bridles insert into a groove around the base of the component to be mounted. In some cases, the base plate of the component to be mounted must be removed for proper usage. BR bridles are sold in sets of four.

BR-U bridles are designed for mounting components directly to tables and breadboards when the base plate cannot be used. BR-U bridles are sold individually.
To choose the correct bridle set for your application consult the chart on the following page which lists some of our more popular combinations.
