We've used neoprene jacketed aluminum wire loom clamps for the past year
with good success.  Vendor is Del City, (800) 654-4757.  They also have a
stainless steel version, if you need.  Their part #2808  (2008-9 in
stainless) is the perfect size to clamp an MC connector tight.  $12.30/100
in aluminum, $27.21 in stainless.

I've gone back to systems after 3 years in the New Mexico sun and seen black
"UV-resistant" zip ties snap when touched.  I've also seen the black plastic
locknuts that ship with BP module cable glands split into quarters on the
same array.

Mother Nature always wins.
