This 12 in nitrogen gas spring (gas strut, lift support) holds heavier lids, RV storage bay doors, boat hatches and lift-up cabinets. It comes in 200 N or 250 N. Buy a pair to mount one on each side and avoid side load.
Closest catalog size: 300 mm. The 12 in length is not an exact catalog match, so only the length, force and pack below are confirmed for this spring.
| Extended length | 12 in (305 mm) |
|---|---|
| Force options | 200 N (45.0 lbf), 250 N (56.2 lbf) |
| Pack | Single (1 spring) or Pair (2 springs) |
Sizing
Force per spring: F1 (N) = 9.81 × (RH × m) / (2 × N × X2) + 5, where m = lid mass in kg, RH = opening length in m, X2 = lever arm in m, and N = number of springs. Round up to the next available force. For a 90° opening, stroke ≈ RH / 3. 1 kg ≈ 10 N ≈ 2.2 lbf.

A gas spring is not a safety component. Where failure would risk health or life, add an independent locking mechanism.
