Portable Tyre Killer

The LZ-SD-JA type puncture and deflation roadblock uses aluminum alloy profiles to form a telescopic frame. The telescopic length can be pulled out freely. The telescopic frame is equipped with 158 sharp three-edged needles with exhaust grooves on the edges. The wheels run over the barricade spikes. Once it enters the tire, it will be deflated and immediately paralyzed and unable to drive. The LZ-SD-JA manual traffic blocking roadblock complies with the relevant standards of "GA/T421-2003 Puncture and Deflation Roadblock";
