Mr. John Lee 

ETl USA, Inc. 

500 N Broadway, Suite 225 

Jericho, NY 11753 

Dear Mr. Lee: 

This letter is in response to your September 26, 2017 request for the Federal Highway 

Administration (FHW A) to review a roadside safety device, hardware, or system for eligibility 

for reimbursement under the Federal-aid highway program. This FHWA letter of eligibility is 

assigned FHWA control number B-291 and is valid until a subsequent letter is issued by FH~A 

that expressly references this device. 

Decision 

The following device is eligible within the length-of-need, with details provided in the form 

which is attached as an integral part of this letter: 

• Road Safety Barrier Roller System Model ET1-GR02-TL4 

Scope of this Letter 

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash 

test and evaluation criteria contained in the American Association of State Highway and 

Transportation Officials'(AASHTO) Manual for Assessing Safety Hardware (MASH). 

However, the FHWA, the Department of Transportation, and the United States Government do 

not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the 

Federal-aid highway program does not establish approval, certification or endorsement of the 

device for any particular purpose or use. 

This letter is not a determination by the FHW A, the Department of Transportation, or the United 

States Government that a vehicle crash involving the device will result in any particular 

outcome, nor is it a guarantee ofthe in-service performance of this device. Proper 

manufacturing, installation, and maintenance are required in order for this device to function as 

tested. 

This finding of eligibility is limited to the crash worthiness of the system and does not cover other 

structural features, nor conformity with the Manual on Uniform Traffic Control Devices. 
2 

Eligibility fo r Reimbursement 

Based solely on a review of crash test results and certifications submitted by the manufacturer, 

and the crash test laboratory, FHW A agrees that the device described herein meets the crash test 

and evaluation criteria of the AASHTO's MASH. Therefore, the device is eligible for 

reimbursement under the Federal-aid highway program if installed under the range of tested 

conditions. 

Name of system: Road Safety Barrier Roller System Model ET1-GR02-TL4 

Type of system: Longitudinal Barrier 

Test Level: MASH Test Level 4 (TL4) 

Testing conducted by: KARCO 

Date ofrequest: September 26, 2017 

Date initially acknowledged: October 1, 2017 

FHW A concurs with the recommendation of the accredited crash testing laboratory on the 

attached form. 

Full Description of the Eligible Device 

The device and supporting documentation, including reports of the crash tests or other testing 

done, videos of any crash testing, and/or drawings of the device, are described in the attached 

form. 

Notice 

This eligibility letter is issued for the subject device as tested. Modifications made to the device 

are not covered by this letter. Any modifications to this device should be submitted to the user 

(i.e., state DOT) as per their requirements. 

You are expected to supply potential users with sufficient information on design, installation and 

maintenance 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 of AASHTO's MASH. 

Issuance of this letter does not convey property rights of any sort or any exclusive privilege. This 

letter is based on the premise that information and reports submitted by you are accurate and 

correct. We reserve the right to modify or revoke this letter if: (1) there are any inaccuracies in 

the information submitted in support of your request for this letter, (2) the qualification testing 

was flawed, (3) in-service performance or other information reveals safety problems, (4) the 

system is significantly different from the version that was crash tested, or (5) any other 

information indicates that the letter was issued in error or otherwise does not reflect full and 

complete information about the crash worthiness of the system.

Standard Provisions 

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

control number B-291 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 upon request. 

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

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

• 	 Ifthe subject device is a patented product it may be considered to be proprietary. If 

proprietary systems are specified by a highway agency for use on Federal-aid projects: 

(a) they must be supplied through 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.

PRODUCT DESCRIPTION 

r. New Hardware or (' Modification to 

Significant Modification Existing Hardware 

The Road Safety Barrier Roller System model ETl-GR02-TL4 is a longitudinal barrier designed to contain, redirect 

and shield vehicles from roadside barriers. The system consisted of alternating long and short posts spaced 1.6 

ft. (0.5 m) apart. The system consisted of two sets of frame rails. The bottom and top frame rails were mounted 

at a height of 13.8 in. (350mm) and 37.4 in. (950 mm) above grade, respectively. The frame rails were mounted 

to the posts by a support and locker assembly. Each assembly was bolted to the posts with four (4) 19x60 bolts. 

The frame rails were 26.2 ft. (8.0 m) long and the splices were placed mid-span between posts. 

The short posts were 720 mm long and were attached to the frame rails by the same support and locker 

assembly as the long posts. Placed over the long and short posts were PVC rollers. The rollers were 18.9 in. (480 

mm) tall and had an outside diameter of 13.6 in. (345 mm). 

CRASH TESTING 

By signature below, the Engineer affiliated with the testing laboratory, agrees in support of this submission that 

all of the critical and relevant crash tests for this device listed above were conducted to meet the MASH test 

criteria. The Engineer has determined that no other crash tests are necessary to determine the device meets
