This compact increaser is ideal for high-rise hose layouts. In the event of stretching short, or if a line extension is needed, this increaser can be used to connect high-rise hose bundles together from the Strahlrohr shutoff discharge. The 111A is unique in that it features knurling instead of rocker lugs to ensure adequate clearance of Strahlrohr bale handles. Consider the 111A an essential addition to your standpipe setup.
