Dear Mr. Eckert: 

We received your correspondence of December 8, 2021 requesting issuance of a reimbursement 

eligibility letter under the Federal-aid highway program for the roadside safety system, device, 

design, product, or hardware (collectively “device”) described below. This letter is assigned 

Federal Highway Administration (FHWA) control number SS-187. 

ELIGIBILITY LETTERS

The FHWA issues Federal-aid reimbursement eligibility letters for new roadside safety devices

that are crash tested in accordance with the industry standard of the American Association of 

State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware 

(MASH). 

FHWA, the Department of Transportation, and the United States (government) do not regulate 

roadside safety devices, crash test facilities, or the manufacturing industry. Issuance of 

eligibility letters is discretionary and provided only as a service to the states. FHWA may, at its 

discretion, decline to issue, revise, or rescind an eligibility letter. Eligibility letters are only 

issued by the FHWA headquarters Office of Safety. 

Eligibility letters are issued only as notice to the states that a device is eligible for reimbursement 

under the Federal-aid highway program. They do not establish approval or certification for any 

other purpose. Issuance of an eligibility letter is not a prerequisite or requirement for state 

transportation agencies seeking to use Federal-aid funds for roadside safety devices. State 

agencies may use a device for which an eligibility letter has not been issued and seek Federal-aid 

reimbursement. 

FEDERAL-AID REIMBURSEMENT

The request for issuance of this letter certified the device was crash tested in accordance with the 

industry standard of AASHTO’s MASH. This eligibility letter is based on that certification and 

the material offered in support of its issuance. The device described below is eligible for 

reimbursement under the Federal-aid highway program. 

October 5, 2022

Name of system: SQR-LOC Perforated Single Post Sign Support System

Type of system: Sign Supoort 

Test Level: Test Level 3

Testing conducted by: Applus IDIADA KARCO Engineering, LLC 

Date of request: December 8, 2021

Information about the device, including material such as the eligibility request, crash test reports, 

drawings, or images are included in one or more attachment(s) to this letter. 

Eligibility letter SS-187 is inapplicable to devices, optional equipment, alternate materials, or 

other features that were not crash tested in accordance with AASHTO’s MASH. 

This letter is issued only for the subject device as crash tested under AASHTO’s MASH. Later 

modification(s) of the device are not eligible for Federal-aid reimbursement under this letter. 

Notice of later modification(s) should be given to transportation agencies, facility owners, and 

operators (collectively “agencies”). 

Agencies should be provided appropriate information about the device’s design, installation, 

maintenance, materials, and mechanical properties. 

Issuance of this letter is discretionary, and it may be revised or rescinded at FHWA’s discretion. 

This letter is not a determination of compliance with the Manual on Uniform Traffic Control 

Devices for Streets and Highways (MUTCD) or ownership of any intellectual property rights. 

This eligibility letter is not a determination by the government that a crash involving the subject 

device will result in any particular outcome. It is limited to only the device’s eligibility for 

Federal-aid reimbursement. 

INTELLECTUAL PROPERTY

Issuance of this eligibility letter does not convey property rights of any sort nor any exclusive 

privilege. This letter is not authorization or consent by the government for the use, manufacture, 

or sale of any patented or proprietary system, device, design, product, or hardware for which the 

requester is not the patent owner. Eligibility letters are not an expression of any view, position, 

or determination by the government as to the validity, scope, or ownership of any intellectual 

property rights to a specific device. These letters do not grant, impute, suggest, or otherwise 

establish any ownership, distribution, or licensing rights to the requester. The government 

expresses no opinion about the intellectual property rights relating to any device for which this or 

any other eligibility letter is issued. 

PUBLIC DISCLOSURE

To prevent any misunderstanding, and as discussed above, this eligibility letter is assigned 

FHWA control number SS-187. It should only be reproduced in full with its attachment(s). This 

letter and the material offered by the requester supporting its issuance is public information. All 

eligibility letters and supporting material are subject to public disclosure under the Freedom of 
3 

Information Act (FOIA). Eligibility letters are available to the public at

PRODUCT DESCRIPTION 

New Hardware or 

Significant Modification

Modification to 

Existing Hardware

The SQR-LOC® Perforated, Single Post Sign Support System consists of one, 2-1/2 inch x 10 gauge perforated 

square steel tube signpost inserted 10-1/2 inches into a 3 inch x 7 gauge square steel tube anchor sleeve. The 

signpost is punched with Ø7/16 inch holes spaced on one inch centers along the length on all four sides. The 

signpost is secured to the anchor sleeve using a Ø5/16 inch corner bolt and nut. The anchor sleeve is 36 inches 

long and embedded in soil with the top 1-1/2 inch above grade. A 48 inch tall x 60 inch wide x 0.080 inch thick 

aluminum sign panel is secured to the signpost with a U-channel and clamp system. The sign is secured to two 

U-channel sections using Ø3/8 inch bolts and nuts. The sign is mounted at a height of 7 ft. above grade to the 

bottom of the sign. The anchor sleeve is fabricated in conformance with ASTM A500. The steel for the signpost 

conforms to ASTM A653.

QMS-FE-051 Rev 0, 6/29/22 
 

INTENDED USE 

The SQR-LOC® perforated steel tubular sign support system is a single post sign support system. 

The system utilizes a drivable anchor sleeve in standard soil. The sign support system was 

successfully crash tested to TL-3 in accordance with MASH 2016 guidelines. This system meets the

requirements of the AASHTO LRFD Specifications for Structural Supports for Highway Signs, 

Luminaires, and Traffic Signals, 1st Edition, 2015. 

FEATURES 

The SQR-LOC® perforated steel tubular sign support system consists of a 2.50 inch 10 GA 

perforated square steel tube signpost and a square steel anchor sleeve (sheet 3 of 4). The signpost 

slides into the anchor sleeve and is secured in place by a 5/16" corner bolt and nut. The drivable 

anchor sleeve is manufactured from 3 inch square 7 GA steel tubing per ASTM A500 and 

galvanized per ASTM A123. The material for the pre-coated steel signpost tubing conforms to 

ASTM A653. The exterior surface is coated with minimum 0.5 mils clear acrylic polymer. 

ELIGIBILITY 

The SQR-LOC® single post, perforated steel tubular sign support system has been tested to MASH 

2016 Test Level 3 and is eligible for Federal reimbursement by FHWA. 

FHWA Eligibility Letter(s): XX-XXX dated ___________ for MASH 2016 Test Level 3.
