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.

A hydraulic mechanism makes these the smoothest and quietest closers we offer for storm doors.

Close storm doors more smoothly than standard spring closers.

There's no need to mount a closer to your door or frame—these take the place of an existing hinge pin.

These closers can replace Yale, Dorma, Falcon, Stanley, Parker, and Cal-Royal models with the same mounting hole pattern.

A built-in stop prevents doors from opening too far—good when wall- or floor-stops can’t be used. Designed for frequently used doors, these closers last twice as long as standard door closers. They can replace Yale, Dorma, Falcon, Stanley, Parker, and Cal-Royal models with the same mounting hole pattern.

No need to drill new holes—these closers have a mounting plate that fits the hole patterns of most closers from Norton, LCN, Yale, Corbin Russwin, and Dorma.

Nudge your door and these openers will open it the rest of the way.

Mechanical operation means these springs have no seals to fail or gas to leak.

Stainless steel construction provides corrosion resistance for use in damp environments.

Often used to open lids, covers, windows, conveyors, and seats, these gas springs function similar to a hatchback opening on a car. They have an eyelet end fitting on each end.

These gas springs have threaded ends so you can use them with any combination of end fittings, studs, and mounting brackets.

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Often used to replace coil springs in metal stamping and die-spring applications, these gas springs match the diameter and stroke length of coil die springs but offer much more force.

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Automatically locking when fully extended and made of 316 stainless steel to resist corrosion, these gas springs protect material and equipment underneath heavy loads in damp environments.

Pair one of these gas springs with a release control to stop and release the gas spring anywhere along the stroke with the push of a button or lever.

Made from stainless steel for excellent corrosion resistance in damp environments.

Attach eyelet end fittings to these brackets to mount gas springs.

Pair these 90° angle offset-arm brackets with ball socket end fittings to mount your gas spring in almost any position.

Stainless steel that’s twice as thick as standard 90° angle ball stud mounting brackets makes these brackets good for high-force applications exposed to damp conditions.

About twice as thick as standard 90° angle ball stud mounting brackets, these brackets are suitable for high-force applications.

Drill mounting holes where you need them—these brackets are made from aluminum, so they’re easy to machine.

Made from stainless steel for excellent corrosion resistance in damp environments.

Since they’re at least twice as thick as standard ball stud mounting brackets, these brackets are best for high-force applications.
