It stands at 932mm tall, is equipped with a standard UK 2.5" female BSRT inlet and two female outlets, and allows simultaneous water flow from both heads. A blanking plug is included, enabling operation as a single outlet when needed. 

The standpipe itself can connect to a 2.5 inch BSRT outlet on the hydrant using Urban Round Thread (URT), and the check valve included is water company approved. It helpfully stops water from running back through the standpipe once it has passed through.
