Kranzle KWS700TS Pressure Washer with Mosmatic Wall Extension and Boom Pole.
For a wall-mounted boom, you need two parts: The MOSMATIC WALL BOOM EXTENSION is mounted to the wall, and then the standard MOSMATIC INLINE CEILING BOOM POLE attaches to that. You will want the Wall Extension to stop about where the center of your vehicle or wash area is, and then the main attached boom will swivel from that point.
The hoses are not included with the boom. You will want to use our 25' KOBRAJET HOSE NO QDs to connect to the boom, and then the same hose as the outlet from the boom to the gun. We don't make them in any other lengths, so for the connection to the gun you will want to have a hydraulics shop cut and refit a new end at the correct length. You will measure from the floor to the tip of the boom, plus 3' for the proper length of that hose to the gun.
Here's a good list to go off of:
