Mr. Ron Faulkenberry 

Gibraltar Global LLC 

1208 Houston Clinton Drive 

Burnet, TX 78611 

United States 

Dear Mr. Faulkenberry: 

On February 27, 2020, The Federal Highway Administration’s Office of Safety issued eligibility 

letter B-316 for the Gibraltar Global TL-4 Cable Barrier System. The Office of Safety has 

recently made modifications to its eligibility letter website to be more consistent with the 2

nd

Edition of American Association of State Highway and Transportation Officials’(AASHTO’s) 

Manual for Assessing Safety Hardware (MASH) and the additional test matrices for cable 

barriers therein. These modifications have necessitated the update of certain eligibility letters 

including B-316. The modification for B-316 consists of adding the phrase “Level Terrain” after 

the original description of the device to indicate the as-tested conditions. 

Please note that this updated letter B-316A will in no way affect the eligibility for the associated 

device as was determined on February 27, 2020. This letter will supersede the original letter B316 in full. 

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: 

• Gibraltar Global TL-4 Cable Barrier System, Level Terrain 

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 FHWA, 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 of the in-service performance of this device. Proper 

U.S. Department 

of Transportation 

Federal Highway 

Administration 
2

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

tested. 

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

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

Eligibility for Reimbursement 

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

and the crash test laboratory, FHWA 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: Gibraltar Global TL-4 Cable Barrier System, Level Terrain 

Type of system: Longitudinal Barrier 

Test Level: MASH Test Level 4 (TL4) 

Testing conducted by: KARCO Engineering 

Date of request: November 02, 2018 

 

FHWA 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 crashworthiness of the system. 

Standard Provisions 

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

control number B-316A 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. 

3 

• This FHW A eligibility letter is not an expression of any Agency view, position, or 

determination of validity, scope, or ownership of any intellectual property rights to a 

specific device or design. Further, this letter does not impute any distribution or licensing 

rights to the requester. This FHW A eligibility letter determination is made based solely 

on the crash-testing information submitted by the requester. The FHW A reserves the 

right to review and revoke an earlier eligibility determination after receipt of subsequent 

information related to crash testing.

PRODUCT DESCRIPTION 

 New Hardware or

Significant Modification 

 Modification to

Existing Hardware 

The Gibraltar Global TL-4 Cable Barrier System is a high tension 4-cable longitudinal barrier. The barrier consists 

of four (4) 0.75 in. (19 mm) steel cables, ( -section steel posts, steel sockets, aluminum hair pins and steel lock 

plates. The ( -section posts were placed on alternate sides of the 4 cables and are held in place by the 

aluminum hair pins. The top two (2) cables of the system were stitched together making the cables alternate in 

the top hairpin location. The hair pins held the cables at 20.0 in (508 mm), 30.0 in (762 mm) and 39.0 in. (991 

mm) above grade. The system can be installed with post spacing ranging from 7 ft. to 21 ft. 

Gibraltar also offers various post and socket options such as concrete socket foundations with steel or plastic 

sockets, driven steel sockets, and direct driven posts. Other options include swaged and wedge-type fittings 

which were installed and crash tested. Pre-stretched and non pre-stretched cable are permissible. 

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 

the MASH criteria.
