Pulling force for return and closing functions.
Horizon supplies traction gas springs, also called tension or pull-type gas springs, for mechanisms that need an inward return force. Threaded-end units and supports with selected end connections are quoted by their working travel, mounting lengths and pull-force requirement.
The pull force, damping requirement and any separate holding function are defined individually for the mechanism.
A traction gas spring is a different design from a compression strut. Turning a compression gas spring around does not reverse its force.

No. A traction spring is designed to exert an inward pulling force. A compression lift support pushes outward even when it is compressed; the same exterior shape or mounting length does not make the two interchangeable.
Yes. A traction spring can be quoted with selected end connections or as a threaded-end component. The rod and body ends are defined separately, including thread or pivot dimensions and the movement required at each joint.
Pulling assistance and speed control are separate requirements. A quote for a return spring identifies the pull force and travel; any required damping or holding function needs its own specification for the complete mechanism.
| Required result | Matching implication |
|---|---|
| Pull toward retraction | Identify a traction / tension design. A compression spring of similar size acts in the opposite direction. |
| Control closing speed | Specify damping separately. Pulling force by itself does not define a controlled speed profile. |
| Hold a position | A return-force requirement is not a positive-locking requirement. State any separate latch or holding function. |
| Fit the mechanism | Check both installed lengths, travel, end fittings and clearances at the start, middle and end positions. |
Use the instructions for the selected traction design. Do not automatically apply the rod-down rule of a conventional compression gas spring.
Avoid bending, twisting or side loading the rod. Connections must move freely throughout the intended travel.
Keep the mechanism within the specified working stroke. Use suitable travel stops and do not overextend the unit.
Support the mechanism independently for installation or service. Protect the polished rod from clamping, impact and scratches.
