What options for securing 4/0 SER at the outdoor service entrance breaker box - Frame house, service switch located on exterior on siding - thanks

Other that the SER straps shown here:

Briscon Products - STRAPS (http://www.brisconelectric.com/STRAPS1.htm#SE)

Or

Briscon - PRODUCT LIST (http://www.brisconelectric.com/lock-over.htm)

PVC conduit two hole straps work very well, I believe either 1" or 1-1/4" straps will fit #4/0 SER cable. They are already gray to match the cable, and plastic that will not corrode.
