- The Mueller® adjustable indicator post has a 24-1/4 in adjustment range and can be easily adjusted in the field without disassembly
- The Mueller® design uses an operating wrench to make the post tamperproof
- Vertical indicator posts are designed to operate non-rising stem (inside screw) gate valves, which are used to control an underground water supply to automatic sprinkler, water spray deluge, foam-water deluge, or standpipe fire protection systems
- They permit operation of underground valves while providing an above ground visual indication as to whether the valves are open or shut, in addition to a means for locking the valves in a particular position
- Indicator posts provide for valve operation from outside of the protected property and therefore, the opportunity for more prompt valve operation in an emergency situation
- Feature a telescoping stem that can be adjusted to its final position without field cutting of the stem
- The telescoping stem also permits easier setting of the “OPEN” and “SHUT” target plates (before the post is extended to its final position)
- Easier adjustment of the post length during the initial installation and ready re-adjustment of the post length, if there is a modification in the location of the final grade
- Indicator posts will accommodate 4 through 14 in post indicator valves (PIV) requiring 14 to 43 turns to open and that are listed or approved for fire protection system service
- Indicator posts are provided "standard order" for use with left hand opening valves
- Indicator posts accept direct attachment of a 1/2 in NPT mounting electric supervisory switching device which can be used by proprietary and central stations to monitor the open position of the indicator post
