More Information

Dual Socket Ratchet Wrenches fit the most popular waterworks fasteners for mechanical joints, flange bolts, repair clamps, service saddles and sleeves. Each wrench also offers a handy switch on the head for safe action reversal. Ratchet wrenches are faster to use than pipe wrenches or adjustable wrenches. 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. LDSSET features three popular dual socket ratchet wrenches in a convenient storage case. LHM2275 has red sockets to identify this tool as suitable for Hymax™ reducer couplings. L2017 features an ergonomic handle grip.

Metric Sizes XTRA Value

Heavy-duty wrench design has two permanent sockets; meaning no lost sockets.
