SureSite Flag Assembly Configuration


Flag channel assemblies are the same for mini, standard, and plastic SureSites.

Plastic flags part numbers begin with PP1. Plastic flags are flipped white-to-orange with rising liquid level and orange-to-white as liquid level falls.

Aluminum flags part numbers begin with AA5. Aluminum flags are flipped silver-to-black with rising liquid level and black-to-silver as liquid level falls.

To complete your part number, the type and length are called out separated by a dash.

PP1-length (0.5” increments)

AA5-length (0.5” increments)

Example part numbers:

PP1-18.5  = 18 ½ inches long plastic flag assembly

AA5-39  = 39 inches long aluminum flag assembly
