BEAM Hose Adapter
Details
The Beam 170106 Hose Adapter often allows you to use an older Beam powerhead with a new hose. Works with newer hoses and powerheads that are standard 2-prong plugs. By adding this adapter to the hose, the older Beam powerhead with a 3-prong cord will plug into the new hose.
If you have a powerhead with a 3-prong plug you will need this adapter.
