Universal Anchor Systems
P.O. Box 3010
Big Spring, Texas 79721-3010

Dear Mr. Reagan:

Your August 1 facsimile transmittal to Mr. Richard Powers of my staff requested the Federal Highway Administration's acceptance of your Universal Anchor System for single and dual-legged sign supports. Subsequent telephone discussions revealed that you sought acceptance of the specific design using schedule 40 steel pipe set in concrete as shown on the right hand side of Enclosure 1. You also submitted preliminary test result summaries sent to you by the Texas Transportation Institute on August 1 (Enclosure 2).

Based on our review of these data, we will offer conditional acceptance of the Universal Anchor System, pending receipt of the final report, crash-test videos, and material specifications for the anchor. Dimensions on the final drawings should be shown in metric units.

Please be aware that this conditional acceptance is based on the summary information you have submitted and it may be rescinded or modified if the final report indicates problems or concerns that were not evident from a review of these preliminary data.

Should you have any questions, please call Mr. Nicholas Artimovich of my staff at (202) 366-1331.

Sincerely yours,

Seppo I. Sillan, Acting Chief
Federal-Aid and Design Division
