REED's L4N1 and L4N1XP Thru-Bolt™ ratchet wrenches feature four sockets on one wrench in a popular dog bone configuration. The sockets are designed to stay on the handle, which means there are no loose sockets to misplace. The length and design of the handle provide maximum leverage. And, the rugged, textured handle grip ensures a secure hold for the operator. Use just one tool to work on mechanical joints and restraints, repair clamps, service saddles, gas/water couplings, flange bolts, friction clamps, hydrant break flanges and some bonnet bolts. Additionally, tightening nuts on long bolts or all-thread rod is never a problem with REED's Thru-Bolt™ sockets which 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. L4N1XP provides superior performance and extra protection as the sealed ratchets keep out most debris and dirt. Regular tool cleaning and maintenance is recommended for both wrench models. These socket wrenches are made in USA.
