Compression Locking Gas Springs 250mm 500N
During closing, internal gas pressure supports the movement like a conventional gas spring. Near the end of the stroke, a dedicated locking sleeve engages and the unit behaves like a solid prop-unlike non-locking gas shocks that can "push back." This makes Land's compression-locking design a smart choice for equipment that must stay shut until intentionally reopened. Material choices include painted steel for general use and SS304/SS316 for marine or wash-down environments. Seal and fluid packages are available for low-temperature or high-duty cycles. Land tunes force, damping, and connector geometry so each gas lift support closes confidently and locks every time.
Key Features & Benefits
Rigid at full compression: Lock engages as the rod bottoms out, preventing re-extension during transit or impact-ideal where a lock-out gas spring feel is required.
Lower operator effort: Nitrogen charge assists the closing motion so heavy covers seat smoothly.
Quiet, controlled finish: Optional hydraulic damping tames the last portion of travel for a premium close.
Built for harsh duty: Black-nitride steel or 316 stainless options resist corrosion; precision seals maintain force over long cycles.
Application-matched: Custom force, stroke, and fittings so your gas strut aligns perfectly with hinge geometry.
OEM-ready by Land: Fast CAD, pilot builds, factory-level pricing, and a 5-year warranty.

End fittings: Ball sockets, eyelets, clevis, threaded M6–M10; quick-release options.
Damping: Standard or soft-close tuning.
Compliance: RoHS/REACH; endurance tested to application.
Applications
- Industrial machine covers & access doors: Hold securely closed in transit or under vibration.
- Vehicle compartments & mobile equipment: Service hatches, battery trays, and tool bays requiring lock-closed security.
- Medical & rehab frames: Sections that must not creep open under patient load.
- Ergonomic fixtures & jigs: Maintain fixed position after clamp-down for repeatable assembly.
- Marine & outdoor enclosures: Hatches exposed to wind and motion-316 recommended.
- Furniture & architectural elements: Fold-down worktops, overhead bins, and instrument lids.
Selection Guide (How to Specify)
- Define the load path: Mass, center of gravity, hinge offset, and closing angle.
- Pick stroke & geometry: Choose stroke to meet closed depth and hardware clearances.
- Set target force: Start with 60–75% of effective load; Land will fine-tune for feel and safety.
- Confirm lock direction: This model locks in compression; ask us about rigid-in-extension if needed.
- Choose materials: Carbon steel for general duty; SS316 for marine/food/chemical exposure.
- Select fittings & brackets: Keep rod in line-avoid side-load for best life.
- Add damping if required: Soft-close feel for delicate equipment or user comfort.
