Reed's L4N1 Thru-Bolt™ ratchet wrench features four sockets on one wrench in a popular dog bone configuration. The sockets stay on the handle, meaning no loose sockets. L4N1 offers rugged construction of its smooth grip handle with a forward/reverse pawl. 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.
