Stop Stick Products

The City of Portland, Oregon is publishing a Notice of Sole Source Procurement for Stop Stick tire deflation and pursuit termination devices on March 14, 2025, with a seven-calendar-day posting period prior to contract award. This is a sole-source procurement under Portland City Code 5.10, with Stop Stick, LTD identified as the sole source and sole distributor.

The scope includes Stop Stick, Piranha, and Terminator tire deflation devices along with associated training kits for deployment in Portland Police Bureau patrol vehicles as pursuit prevention and termination tools. The justification rests on a U.S. Department of Homeland Security SAVER assessment that rated the Stop Stick system higher than competitor products in capability, deployability, maintainability, and safety—with safety as the highest-weighted category. Competitor products demonstrated significant safety concerns during field testing, including spikes becoming projectiles during deployment.

The estimated contract value is $625,000 over a five-year term with no renewal options. The vendor has indicated its intent to provide all products and materials without utilizing subcontractors. Questions should be directed to Mark Ariza, Procurement Analyst, at 503-823-1885 or Mark.Ariza@portlandoregon.gov. Any firm adversely affected by the contract award has seven days from the issuance of this notice to file a written protest with the Chief Procurement Officer.
