The PC4501 · Protection

The Protection

Each standard alone leaves part of the leg uncovered. The PC4501 is certified to both, so it combines the higher chain speed and calf protection of the Canadian standard with the left-side coverage and angled cut test of the US standard.

Protective pad coverage compared. Canadian standard only (ASTM F3325 Class A, F3324): 3,000 ft/min, 90° cut only, front and rear calf, no left side. US standard only (ASTM F1897, F1414): 2,750 ft/min, 45° and 90° cuts, front and left side, no rear calf. PC4501, UL certified to all four: 3,000 ft/min, 45° and 90° cuts, front, left side and rear calf.

Why We Chose Dual Certification

Together, the Canadian and American certifications are greater than the sum of their parts. The Canadian certification tests at a higher chain speed and adds calf protection; the US certification adds left-side coverage and an angled cut test. The result: more of the leg protected than either certification alone.
