Dear Mr. Groves:

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

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

program.

Name of system: J-J Hooks Pin Down F-Shape Barrier

Type of system: Concrete Portable Barrier

Test Level: AASHTO MASH Test Level 3

Testing conducted by: Texas Transportation Institute (TTI)

Task Force 13 Designator: SWC02

Date of request: October 4, 2012

Date initially acknowledged: October 5, 2012

Date of completed package: December 13, 2012 

Decision:

The following devices are eligible, with details provided in the attached forms which are an 

integral part of this letter:

• J-J Hooks Pin Down F-Shape Barrier for Asphalt Surface

Based on a review of crash test results and embedment computational analysis submitted by the 

manufacturer certifying the device described herein meets the crash test and evaluation criteria of 

the American Association of State Highway and Transportation Officials’ Manual for Assessing 

Safety Hardware (MASH), 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 FHWA for any particular purpose or use.

The FHWA, the Department of Transportation, 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

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

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

Transportation Officials’ Manual for Assessing Safety Hardware (MASH). 

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 FHWA eligibility letters:

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

used for the purpose of the 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 of the 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 of the MASH.

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

B-52C 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 and 

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

• The J-J Hooks are considered 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 
3

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.

Sincerely yours,
