Type A-325 hardware is utilized during the reflector attachment to the ground mount. Use of A-325 hardware eliminates slippage between mating surfaces under high loading conditions as well as the need for future retightening.

CAUTION: Adhere to any special instructions sten- ciled on crate relative to crate opening, contents removal and/or personnel safety.
