Dear Mr. Christensen:
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:

  	 MB-350 BarrierType of system:

  	 Water Filled BarrierTest Level:

  	 NCHRP Report 350 Test Level 3Testing conducted by:

  	 N/ADate of request:

  	 December 5, 2011 and February 13, 2013Date initially acknowledged:

  	 December 6, 2011Date of completed package:

  	 February 26, 2013**Decision:**
  The following device is eligible, with details provided in  the form (Attachment 1) and a narrative description (Attachment 2) which are  included as integral parts of this letter:
  Off The Wall MB-350 Water Filled Barrier with hitch pin connection and steel strap under the unitsBased on a review of prior crash test results and  documentation on proposed modifications submitted by the manufacturer  certifying the device described herein meets the crash test and evaluation  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 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**
    Roadside safety devices should meet the guidelines  contained in the National Cooperative Highway Research Program (NCHRP) Report  350 or the American Association of State Highway and  Transportation Officials' Manual for Assessing Safety Hardware (MASH).
  **Description**
    On February 26,  2013, you provided the attached description of the evolution of the MB350  barrier.  In addition, on September 21,  2007, you provided information indicating the strength of the hitch pin was a  100,000 psi yield strength which exceeded the 85,000 psi yield of the Grade 5  bolt that was used in the original crash testing.
  **Findings**
    Therefore, the system described and detailed in the  attached form is eligible for reimbursement and may be installed under the  range of conditions under which the original device was tested.
  Please note the following standard provisions that apply  to FHWA eligibility letters:
  This finding of eligibility is limited to crash characteristics and does not cover the structural features of the systems, nor conformity with the Manual on Uniform Traffic Control Devices.
    Any changes that may influence the crash characteristics of the system 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 will be expected to supply potential users with sufficient information on design and installation requirements to ensure proper performance.
    You will be 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 crash test requirements of the NCHRP Report 350.
    To prevent misunderstanding by others, this letter of eligibility is designated as number B-34H 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 is neither prepared nor required to become involved in issues concerning patent law. Patent issues, if any, are to be resolved by the applicant.
    Off The Wall water-filled barriers are patented products and 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 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.
    Because some water ballasted barriers and channelizers  are similar in appearance, the FHWA recommends labeling each unit or module to  indicate limitations on use.  When used  as a barrier all hardware, both internal and external that was used in the  crash testing, shall be installed per the manufacturer's instructions.  Recommended guidance for such labels may be  found on the web site of the AASHTO/AGC/ARTBA Task Force 13 at  http://www.aashtotf13.org.Sincerely yours,
