Mr. Artimovich,
We respectively request The Federal Highway Administration review for approval our X Foot print sign stand in consideration for a Safety Acceptance Letter.
The Sign Stand is a variation of two FHW A approved stands, the SZ-460 found in letter WZ-67 along with the SZ-412-2S found in WZ-242, along with other industry standard sign stands known as X foot print and or compact sign stands for exclusive use in displaying roll up signs up to 48" diamond or 16 square feet or smaller, of standard configuration.
Based on a review of comparable subject portable sign stands to prior crash test results as detailed in the WZ Letters previously mentioned along with the attached Karco Engineering letter referencing the NEW TEST performance of the two piece mast verses the one piece mast we are convinced that using the two piece mast on the SZ 412 series X foot print stand verses the single piece mast will not change the strength or integrity of the unit as a whole.
It will allow for better storage, ease of shipping and handling while maintaining the same high quality standards for safety on our roadways while meeting the designed product class.
Also attached you will find the application, drawings and the Karco Engineering Data letter.
Please feel free to contact me at any time with questions you may have.
Regards
/s/ Chris Goode
