This extendable ratchet stretches to 12.25 inches for added leverage and collapses to a compact length of 8.4 inches for work in confined spaces. A spring-loaded ring locks the handle into four positions. A 72-tooth reversible ratchet mechanism clicks with only 5 degrees of handle swing for work in confined areas. The low profile enclosed head design keeps dirt out and fits into narrow spaces. Forged from chrome vanadium alloy steel and heat-treated for superior strength and durability. The knurled handle provides a sure, non-slip grip. Precisions chamfered 3/8" square drive lead-in for fast and easy placement of sockets and accessories onto the drive square. And, the full polished chrome finish easily wipes clean of oil and dirt.
