Storm Door and Gate Closers

Torsion Spring Storm Door and Gate Closers

Mounted diagonally so one end is higher than the other, the motion of an opening door tightens the torsion spring; as it unwinds, it closes the door.

Adjustable-Force Extension Spring
Storm Door and Gate Closers

These closers consist of two interconnected springs—twist them to adjust closing force. The springs retract to pull storm doors and gates closed.

Extension Spring Storm Door and Gate Closers

Torsion Springs

Corrosion-Resistant Torsion Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs.

Made-to-Order Torsion Springs

Whatever the size, we'll get the spring you need.

Pulling Gas Springs

Also known as tension and traction gas springs, these work in the opposite direction of other gas springs. Similar to a screen door closing, they're used to assist in closing covers, hoods, and doors.
