Offsetting the System
The REACT 350
®
II, with a Self-Contained Backup, may be offset from the center of the roadside
obstacle if space permits. Offsetting may be necessary for two reasons:
1) To shield a fixed object wider than 200 mm [8”]
2) If bidirectional traffic is present
When offsetting the system, align the vertical face of the Backup structure with the face of the
barrier (Figure 9). With this method, REACT 350
® II with Self-Contained Backup may shield
roadside features up to 610 mm [24”].
Important:
A Concrete Backup may be required if a wider roadside feature or
bidirectional traffic are present. Please contact Trinity Highway Customer Service
for additional information
(p. 3).

Concrete Backup
The REACT 350 ® II system is also intended to mount directly to a new or existing Concrete
Backup. This type of system requires slightly more assembly time, as the cables must be
assembled on site (p. 27).
Existing Concrete Backups must be a minimum of 40” [1000 mm] high, 24” [610 mm] long, and
30” [762 mm] to 36” [914 mm] wide, with 28-day strength of 4000 psi [28 MPa] and fully reinforced.
If your existing structure does not meet these minimums, special hardware and designs may be
available for them. Contact Trinity Highway Customer Service Department if you have questions
concerning Concrete Backup requirements (p. 3).
