Unique accessibility in limited space applications

Ratchet Nutrunner LBR

The Atlas Copco LBR ratchet nutrunner is designed for tightening and loosening in locations where clearance is extremely limited -- the low-profile ratchet head accesses fasteners in spaces that straight or angle nutrunners cannot reach. Built-in reverse makes the LBR efficient in both directions without tool changes, and the design requires minimal adjustment to switch between tightening and loosening, keeping cycle times low in confined-access assembly and maintenance applications.

  • Low-profile ratchet head for very low clearance fastener access
  • Reaches locations inaccessible to straight or angle nutrunners
  • Built-in reverse for efficient tightening and loosening without tool changes
  • Minimal adjustment required between operations for fast cycle times
