Reed offers four dual socket ratchet wrench combinations. L1817 incorporates the popular 1 1/8" and 1 1/16" sockets into one handy tool. Gas utilities/contractors and waterworks should especially like the L1817 which is used for bolted gas couplings and most full circle repair clamps, in addition to water services couplings, flange bolts, and service saddles. LHM2275 (3/4" + 7/8" sockets) has red sockets to identify this tool as suitable for Hymax reducer couplings. Reed's other dual socket ratchet wrenches are the L2017 (1 1/4" + 1 1/16" sockets) and the L1815 (1 1/8" + 15/16" sockets). Of rugged construction, each wrench also offers a handy switch on the head for safe action reversal. Thru-bolt sockets work by letting the bolt pass completely through the socket and arm head so nuts can be worked on any threaded length. Thru-bolt sockets replace the need for separate regular and deep sockets. These wrenches are made in USA.
