Extension Springs with Loop Ends
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Rate is the amount of force required for every inch of extension.
Zinc-plated springs have mild corrosion resistance.

Overload-Prevention Extension Springs
These zinc-plated steel springs have mild corrosion resistance. All have drawbars to prevent overextending, which can cause failure.

Corrosion-Resistant
Overload-Prevention Extension Springs
Made of stainless steel, these springs are more corrosion resistant than steel extension springs. All have drawbars to prevent overextending, which can cause failure.
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Rate is the amount of force required for every inch of extension.

Linear Wave Springs
Similar to disc springs, these linear springs are good for absorbing vibration and filling in gaps along the length of an object. Their thin profile allows them to fit in tight spots.

Hydraulic Gate Closers
With a hydraulic mechanism, these are the smoothest and quietest closers we offer for gates. They are reversible for right or left door-swing directions.
