Adjustable Force Tension Springs

Ameritool adjustable force tension springs are made from 316 stainless steel. Just like the adjustable force gas springs the pressure on these can be reduced by the user with no tools required. The force on these springs pulls the piston rod inward, operating in the opposite direction of standard gas springs. Great for use on doors, lids, hatches, and hoods that need to stay closed or would use assistance while closing. In its relaxed state the spring is compressed. You must pull to extend.
• These units can withstand a wide range of temperatures from -40°F to 300°F (-40°C to 148°C)
