Barrier Systems, Inc. 


3333 Vaca Valley Parkway, Suite 800 


Vacaville, CA 95688 


Dear Mr. Dyke: 


This letter is in response to your request for the Federal Highway Administration (FHW A) to 


review a roadside safety system for eligibility for reimbursement under the Federal-aid highway 


program. 


Name of system: X-Lite Tangent (TX) and X-Lite Flared (FX) - Modified 

Type of system: W-Beam Guardrail Terminal 

Test Level: NCHRP 350 Test Level 3 (TL-3) 

Testing conducted by: Safe Technologies, Inc. 

Task Force 13 Designator: SEW23B Tangent; SEW24B Flared 

Date ofrequest: March 6, 2013 

Date initially acknowledged: March 6, 2013 

Decision: 


The following device is eligible, with details provided in the form which is attached as an 


integral part of this letter: 


• X-Lite Flared (FX) and Tangent (TX), both modified with aluminum clip 

Based on a review of crash test results submitted by the manufacturer certifying the device 

described herein meets the crashw01ihiness criteria of the National Cooperative Highway 

Research Program (NCHRP) Report 350, the device is eligible for reimbursement under the 

Federal-aid highway program. Eligibility for reimbursement under the Federal-aid highway 

program does not establish approval or endorsement by the FHW A for any patiicular purpose or 

use. The FHWA, the Department ofTranspo1iation, and the United States Government do not 

endorse products or services and the issuance of a reimbursement eligibility letter is not an 

endorsement of any product or service. 

Requirements 

Roadside safety devices should meet the guidelines contained in NCHRP Report 350 (Report 

350) if tested prior to January 1, 2011 , or the American Association of State Highway and 

Transpo1iation Officials' Manual for Assessing Safety Hardware (MASH) if tested after that 

date. The FHWA Memorandum "Identifying Acceptable Highway Safety Features", dated July 

25, 1997, provides further guidance on crash testing requirements of longitudinal baniers.

Description 


The device and supporting documentation are described in the attached form. 


Summary and Standard Provisions 


Therefore, the system described and detailed in the attached form is eligible for reimbursement 


and may be installed under the range of conditions tested. 


Please note the following standard provisions that apply to FHW A eligibility letters: 


• 	 This letter provides a AASHTO/ARTBA/AGC Task Force 13 designator that 

should be used for the purpose ofthe creation of a new and/ or the update of existing 

Task Force 13 drawing for posting on the on-line 'Guide to Standardized Highway 

Barrier Hardware' currently referenced in AASHTO Roadside Design Guide. 

• 	 This finding of eligibility does not cover other structural features ofthe systems, 

nor conformity with the Manual on Uniform Traffic Control Devices. 

• 	 Any changes that may influence system conformance with MASH will require a 

new reimbursement eligibility letter. 

• 	 Should the FHWA discover that the qualification testing was flawed, that in-service 

performance reveals safety problems, or that the system is significantly different 

from the version that was crash tested, we reserve the right to modify or revoke this 

letter. 

• 	 You are expected to supply potential users with sufficient information on design 

and installation requirements to ensure proper performance. 

• 	 You are expected to certify to potential users that the hardware furnished has the 

same chemistry, mechanical properties, and geometry as that submitted for review, 

and that it will meet the test and evaluation criteria ofthe MASH. 

• 	 To prevent misunderstanding by others, this letter of eligibility is designated as 

number CC-120A and shall not be reproduced except in full. This letter and the test 

documentation upon which it is based are public information. All such letters and 

documentation may be reviewed at our office upon request. 

• 	 This letter shall not be construed as authorization or consent by the FHWA to use, 

manufacture, or sell any patented system for which the applicant is not the patent 

holder. The FHWA does not become involved in issues concerning patent law. 

Patent issues, if any, are to be resolved by the applicant.

• 	 The X-Lite Tangent (TX) Modified, X-Lite Flared (FX) Modified Terminals are 

patented products and considered proprietary. Ifproprietary systems are specified 

by a highway agency for use on Federal-aid projects: (a) they must be supplied 

tlu·ough competitive bidding with equally suitable unpatented items; (b) the 

highway agency must certify that they are essential for synchronization with the 

existing highway facilities or that no equally suitable alternative exists; or (c) they 

must be used for research or for a distinctive type of construction on relatively short 

sections of road for experimental purposes. Our regulations concerning proprietary 

products are contained in Title 23, Code of Federal Regulations, Section 635.411.

The X-Lite system utilizes a cable connected between post 2 and the front of the second rail to provide tension 

to the system for lateral impacts. Upon frontal impacts, the cable releases, permitting the system to telescope 

rearward. 

The proposed modification to the X-Lite (FX/TX) system Is to incorporate a lightweight aluminum clip to the 

cable attachment at post number 2. The retaining clip ensures positive engagement of the cable at post 2 in 

the case that tension in the cable is lost. During a frontal Impact, the clip easily yields and permits the cable to 

release. 

The retaining clip is a safety measure designed to reduce risk of improper installation and construction creep. 

The modification does not effect the impact performance of the system. To demonstrate the proper function 

ofthe retaining clip, a full scale impact test was performed by Safe Technologies, Inc. on the cable release 

mechanism. A surrogate vehicle (bogie) was used to impact post 2 and trigger the cable release with the 

retaining clip installed. The bogie weight is 2000kg and was traveling at approximately 30km/hr with no offset 

or angle. 

As demonstrated in the attached video, the retaining clip does not effect the release of the cable during an 

impact and therefore does not adversely effect the performance of the X-Lite (FX/TX} system. A drawing of the 

proposed retaining clip and application is included with this submittal.
