Facom’s precision engineered Ratchet Ring spanners have a compact ring head which perfectly replaces the ratchet and socket combination and provides the advantages of an extra low-profile ratchet. They have extra thin walls for the tightest clearances and optimum diameter for an unbeatably compact design. The ratchet operates in 5° increments enabling quick tightening and loosening in the most difficult conditions. Because of their low profile they are ideal for low clearance applications.
