Mr. Matthew Schindler 

QWICK KURB, INC. 

1916 US Highway 41 South 

Ruskin, FL. 33570 

Dear Mr. Schindler: 

This letter is in response to your January 2, 2019 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 FHW A control number WZ-378 and is valid until a subsequent letter is issued by 

FHW A that expressly references this device. 

Decision 

The following device is eligible within with details provided in the form which is attached as an 

integral part of this letter: 

• QWICK KURB Stand Alone Long Base with Ll04 MEGA-MARKER, freestanding 

(SlenderBender) Longitudinal Channelizer 

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 of the 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 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, 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 oftested 

conditions.

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

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 WZ-378 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. 

• 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. 

• 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.
