Dear Mr. Eckert:
This letter is in response to your December 16, 2015 request  for the Federal Highway Administration (FHWA) 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 CC-57E and is valid until a  subsequent letter is issued by FHWA that expressly references this device
**Decision**
The following devices are eligible, with details provided in the form which is attached as an integral part of this letter:
QuadGuard® Elite System Modification***Scope of this  Letter***
To  be found eligible for Federal-aid funding, roadside safety devices should meet  the applicable crash test and evaluation criteria in place at the time the  device, hardware or system is initially presented to FHWA for an eligibility  determination. The applicable crash test  and evaluation criteria is contained in the National Cooperative Highway  Research Program (NCHRP) Report 350 (Report 350).
The  FHWA, the Department of Transportation, and the United States Government do not  regulate the manufacture of roadside safety devices. The determination of eligibility for  Federal-aid reimbursement contained in this letter is based solely on a review  of crash test results and certifications submitted by the manufacturer, and the  crash test laboratory.
This  eligibility letter does not establish approval, certification or endorsement of  the device for any particular purpose or use.
Proper  manufacturing, installation, and maintenance are required for this device to  function as tested. Even so, there are multiple  factors involved in a vehicle crash such as vehicle speed or the aspect of the  vehicle to the device at the time of impact that can influence the outcome of a  vehicle crash with any roadside hardware.  This letter is not a determination by the FHWA, the Department of  Transportation, or the United States Government that a vehicle crash involving  this device will result in any particular outcome, nor is it a guarantee of the  in-service performance of this device.
This finding of eligibility is limited to the device's compliance, at the time of testing, with the  applicable crash test and evaluation criteria.  It does not cover other structural features, nor conformity with the  Manual on Uniform Traffic Control Devices.

***Eligibility for  Reimbursement***
FHWA previously issued an eligibility letter for the  roadside safety device, hardware or system described in FHWA eligibility letter  with control number [insert control number]. This letter identifies a  modification to that roadside safety device, hardware or system.
The original roadside safety device information is provided  here:
Name of system:
QuadGuard	EliteType of system:
  Crash CushionDate of original request:
  September 8, 1998Date of original FHWA eligibility letter:
December 30, 1998FHWA Control number:
CC-57The pending modification(s) consists of the following changes:
Removed belt  nose pullout bracket slots.
  Lengthened threaded stud on the nose cylinder  to diaphragm mounting hardware.
  Updated stamping of logo on nose cylinder and  increased nose cylinder attachment hole clearance.
  Revised size of restoration limiting chain  bracket attachment holes in QuadBeam panels from 22millimeter diameter to  22millimeter × 28millimeter slots.Based on the crash test results and/or certifications submitted  by the manufacturer and the crash test laboratory, FHWA finds that the device  described herein meets the crash test and evaluation criteria of National Cooperative Highway  Research Program (NCHRP) Report 350. Therefore, the device with the above listed  modifications is eligible for reimbursement under the Federal-aid highway  program.
It  is the responsibility of the user of the hardware, the manufacturer of the  hardware, and the contractor installing this device to ensure that this device  is appropriate for the location, and installed and maintained properly.

***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***
If  a manufacturer makes any modification to any roadside safety hardware that has  an existing eligibility letter from FHWA, the manufacturer must notify FHWA of  such modification. Information that describes  the significance of a modification is located in FHWA's  policy memo Roadside Safety Hardware-Federal-aid Reimbursement Eligibility  Process dated May 21, 2012. The notice  of any modification(s) to a device must be accompanied by:

Significant  modifications – For these  modifications, crash test results must be submitted with accompanying  documentation and videos
    Non-signification  modifications – For these  modifications, a statement from the crash test laboratory on the potential effect  of the modification on the ability of the device to meet the relevant crash  test criteria, and
    a  request for FHWA's review for  continued eligibility for reimbursement.FHWA's determination of continued  eligibility for the modified hardware will be based on whether the modified  hardware will continue to meet the relevant crash test criteria.
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 the Report  350.
We reserve the right to modify or revoke this letter  should the FHWA determine that the qualification testing was flawed, that  in-service performance of this device reveals safety problems, or that the  system is different from what is described in this letter and its accompanying  documentation.
***Standard Provisions***

This letter provides an 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 an existing Task Force 13 drawing for posting on the  on-line ‘Guide to Standardized Highway Barrier Hardware’  currently referenced in AASHTO Roadside Design Guide.

  To prevent misunderstanding by others, this letter of  eligibility designated as FHWA control number CC-57E shall only be reproduced  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 FHWA to use, manufacture, or sell any patented  system for which the applicant is not the patent holder.
  If the 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. Regulations  concerning proprietary products are contained in Title 23, Code of Federal  Regulations, Section 635.411.Sincerely yours,
