A-2® frames are constructed with the patented SprinGuard™ lens retention system.
SprinGuard secures the lenses efficiently with less frame mass. A-2 eyewear is thinner
and lighter yet, incredibly, it exceeds the ANSI Z87.1 2003 impact standard
by a wide margin.

Patented SprinGuard™ flat posterior lens lip
design provides superior lens retention. A-2
requires that the lens be edged with a
SprinGuard bevel for the ultimate in safety
protection.

EZ-shield™ rivet less side shields provide the
ultimate in easy permanent attachment.

A safety frame is only as durable as the screws
used in closure barrels and hinges. SAFE-LOK™
locking screws stay in and stay tight for lasting protection.
