[RE-wrenches] lay in lugs

[Dave Click]

Burndy's changed its part# from the CL50-DB-T to the CL50-1TN. Still 
direct-burial, still tin-plated, still "commonly used for solar panel 
grounding." The tech support guy I spoke with last December said that 
their lugs are now all direct-burial, so they decided that there wasn't 
a point in keeping up the DB designation.
