Installation Procedures
Use of A325 hardware eliminates slippage between mating surfaces under high loading
conditions as well as the need for future retightening. Refer to the A325 tensioning pro-
cedure in preceding installation text. CAUTION: Adhere to any special instructions sten-
ciled on crate relative to crate opening, contents removal and/or personnel safety.
Note: Install reflector/back structure assembly only when winds are less than 15 mph to
prevent damage to reflector panels and ease overall assembly.
