Lift-Off Enclosure
CONCRETE ALREADY POURED? NOT A PROBLEM!
The design of the Lift-off Backflow Preventer Enclosure allows for more latitude in installation. It can be mounted to existing concrete or any other hard service. This feature is very desirable when there is a need to protect existing equipment. In addition, since one size Lift-Off can cover several different sizes of valves or equipment, a Lift-Off can cost less than a standard enclosure. The Lift-Off - like all other Le Meur Enclosures - can be used for a variety of applications.
No Frame: Body A366 Sht., 1-1/2” #9 flattened Expanded Metal with A366 Sht.,16 GA.
End Panels: End panels sill covered with closed cell neoprene to prevent abrading finish.
No Hinges:Two Lock Guard with Staples located on each end providing extra security.
Installed Height - 0", Sits on top of Concrete:We recommend allowing at least 1” clearance on each side & each end to avoid damaging the finish when removing. Height requires less clearance.
