Tool box has the "usual" stuff.
wrenches that fit all the fittings and QDs..and of course a "West Virginia socket set"
(that's a Cresent wrench to you guys south of Mason Dixon)
Chanel-locks, and vise grips , screw divers, hex wrenches (allen wrenches to the "unwashed")
Four-Way faucet wrench
Teflon tape , misc fittings and QDs
jets and strainers
spotters ..we don't carry a bunch in.
During walk thru on res, or set up on empties, you get a pretty good idea what spotters or specialty chems you'll need to bring in.
otherwise, 'bout the only spotter that comes in "all the time" is a bar of Fels
..L.T.A.
