Model-specific orientation
Use the instructions for the selected traction design. Do not automatically apply the rod-down rule of a conventional compression gas spring.
PRODUCT RANGE
Tension & Traction Gas Springs (Pull-Type Gas Struts)
Traction gas springs—also called tension or pull-type gas struts—work the opposite way to a standard gas strut: the rod is pulled out and the spring pulls it back in. Use them where a load must be pulled closed or returned to its start position.
Traction Gas Springs
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.

MOTION DIRECTION
Tension vs compression gas springs
A traction gas spring is a different design from a compression strut. Turning a compression gas spring around does not reverse its force.
TYPICAL USES
Where tension gas springs are used
Pulling lids, flaps and doors closed
Where a cover should be drawn shut rather than pushed open, a tension gas spring pulls its rod back into the cylinder and assists the closing movement.
Return mechanisms
Mechanisms that need an inward force to return to their start position. Specify the pull force and travel, and state any damping or holding function separately.

Is a traction gas spring a compressed version of a lift support?
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.
Can you include the end connections?
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.
Does pulling force also control the closing speed?
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.
MATCHING DETAILS
Pulling, damping and locking are separate decisions.
| 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. |
Installation and movement checks
Aligned joints
Avoid bending, twisting or side loading the rod. Connections must move freely throughout the intended travel.
Travel limits
Keep the mechanism within the specified working stroke. Use suitable travel stops and do not overextend the unit.
Supported handling
Support the mechanism independently for installation or service. Protect the polished rod from clamping, impact and scratches.
