For EMS by EMS

In use by New York City EMTs, Paramedics and ESU Tactical Medics, who have no time nor tolerance for tools that fail or don't work, this wrench has been designed and field tested by professional EMS for EMS.

The TK 1 and TK 2 are hands down the best Oxygen Tank Keys available.

WHY THE WANTYNU WRENCH IS BETTER: The TK1 and TK2 have a unique Patent Pending design made from strong, lightweight and extremely durable aircraft quality aluminum alloy.
