The Stanley BR87 Underwater Breaker is the largest in the Stanley range and is used for the heaviest of breaking and for ground rod tasks.
The BR87 Breaker is a T handle design with a large trigger for fine control and a diaphragm accumulator for increased blow force. The BR87 is fitted with a feathering trigger controlling the speed of the breaker, this makes start up and initial tool placement easy. As with all Stanley Breakers this model can handle back pressures of up to 250psi which is particularly useful when running long hose lengths.
