Brackets and Compasses for Lockers

Locker arms and compasses are essential accessories for ensuring controlled, safe, and durable opening of hatches, lockers, doors, and covers on board.

⚙️ BRACKETS FOR LOCKERS

Lift arms (or pistons) help lift and support lids or hatches, preventing accidental closing and facilitating access.

✅ Main types:

Type Characteristics Typical use
Gas-assisted (shock absorbers) They contain pressurized gas, smooth opening Heavy lockers, engine covers
Friction mechanics With internal clutch, they stop in any position Lighter doors
Spring loaded Constant thrust, cheaper Small or vertical lockers

📐 Technical specifications:

  • Force (N): 100 to 800 N depending on the weight of the lid

  • Stroke: variable extension length (e.g. 200 mm, 300 mm)

  • Materials: galvanized steel, AISI 316 stainless steel (recommended for marine environments)

  • Connections: ball, eyelet or adjustable joint

🛠️ Tips:

  • Always check the weight and length of the lid

  • Install two symmetrical stays on large or heavy lockers

  • In saline environments, choose only AISI 316 stainless steel or with an anti-corrosion finish
