Please read this owner’s manual and keep it at 

hand for reference.
From typical fence system applications such as 

grooving, dadoing, rabbeting, edge forming, and 

ripping to advanced joinery functions, your new 

INCRA LS Positioner represents the 

ultimate in quality precision 

tooling for your dream 

shop.  Incra’s patented lead 

screw driven positioning 

element sets a new 

standard for positioning 

accuracy guaranteeing 

fence placement to within 

two thousandths of an inch 

over the full range of the 

fence with zero repeatability error.  

This translates to perfect cutting results, 

regardless of skill level – first time, every time.  If 

you are interested in joinery for your next project, you 

need not look further than your new LS Positioner for 

superior box joint and dovetail capability.  Whether 

you are cutting a simple equally spaced box joint, 

or the exquisite INCRA Double Dovetail, you’ll find 

the simplicity of our template guided joinery system 

makes other joint making tools obsolete.
