The LaborGrip has been designed with extra strength springs. These springs are built for pressure between 8-12 lbs.
You can remove the rubber handle of your LaborGrip to adjust the spring tension. We highly suggest using a simple pair of pliers to appropriately grip the tension knobs. You can turn tension knobs clockwise to add tension and counter-clockwise to remove tension.
All LaborGrip products include packaging with simple instructions for use. You can also print out the complete LaborGrip manual here.
All LaborGrip products come with a 1-year manufacturer warranty. You can read more about the warranty in the user manual.
