Sprinkler Shut-Off Tool

The Safety Technology International STI-QT is a 12 in steel plier designed to stop water flow on many 1/2 in and 3/4 in sprinkler heads. Its V-shaped jaws and locking mechanism allow one-hand operation for fast emergency shut-off. A tether-ready handle helps prevent drops during overhead work.

Maintenance Crews and Irrigation Techs

Suits technicians who need a compact, non-insulated tool for immediate water control on standard rotor and spray heads. Not suited for electrical work requiring insulated grips or for systems using proprietary head designs that fall outside the stated 1/2 in and 3/4 in compatibility.

12 in Overall Length

The fixed 12 in length determines reach into valve boxes and around landscaping obstacles. Buyers must confirm this dimension matches their access constraints before purchase.

Questions about this item

How do I lock the jaws on the STI-QT Quick Stop Sprinkler Tool so it grips a sprinkler head without slipping?

Squeeze the handles until the V-shaped jaws clamp the sprinkler head, then push the lever forward to engage the locking mechanism; the tool will stay clamped until you release the lever.

Will the plain natural handle on the STI-QT need any lubrication or grip replacement over time?

The plain natural handle has no rubber or coating to wear out, so no grip replacement is needed; occasional light oil on the pivot and lever keeps the action smooth.

How long can I keep the STI-QT clamped on a sprinkler head before the lever or jaws start to loosen under vibration?

The locking lever is designed to hold indefinitely under normal water pressure and vibration; it will not loosen until you manually release the lever.
