QuadGuard® II

Products / Impact Attenuators / QuadGuard


QUADGUARD®II CRASH CUSHION  family has evolved again! Using the existing framework of the QuadGuard, the QuadGuard II provides TL-2 and TL-3 protection using less length.

The TL-2 QuadGuard II is 25% shorter than the original QuadGuard measuring less than 3m (10’). The TL-3 model is also nearly a meter, 3 feet, shorter than its predecessor.

The only modifications are the addition of the revolutionary Steel Nose, and the monorail Guide Stabilizers. The remaining components are identical to the existing NCHRP 350 systems that have been installed globally since the mid 1990’s.

The QuadGuard II will telescope rearward on head-on impacts by both the light car and the high center-of-gravity pickup truck at speeds up to 100 km/h (62 mph) and safely redirect errant vehicles on impact up to 20 angles into the side of the unit without gating.
