• P: 42 mm

Typical applications

This compass is designed for uses and where a spring support is needed for opening and movement control. In nautical and onboard plant engineering, it can be used, for example, on:

• Hatches of lockers and technical compartments
• Doors for access to systems and inspections
• Hatches or opening panels that require an assistance element for opening

The presence of attachment accessories (forked clevis and “L” bracket) makes the product suitable when a solution already prepared for mounting is desired, without having to separately source compatible components.

Operational advantages

Stainless steel and completeness of supply

• Stainless steel material: common choice in contexts where the hardware is exposed to humidity and continuous use.
• Ready-to-install kit: terminals and fixing accessories included simplify the mounting process.
• Spring configuration: useful for managing the opening of hatches with elastic behavior.

Integrated safety cable

The stainless steel safety cable is a functional element that helps to prevent spring elongation. In applications where the hatch is frequently opened, this feature can be particularly appreciated for routine maintenance and stability of the configuration over time.

Usage and installation notes

Checks before purchase

To correctly select a spring compass, it is advisable to check:

• Available dimensions on the hatch and on the fixed structure (clearances and fixing points).
• Type of terminals required by the installation: in this variant they are C and D.
• Maneuvering space during opening/closing, to avoid interference with cables, seals, or compartment edges.

General installation instructions

The assembly is generally carried out by fixing the two ends of the compass to the designated points on the hatch and frame using the supplied accessories (forked clevis and “L” bracket). For a neat result:

• Correctly align the anchoring points to allow smooth movement.
• Check that the compass operates without abnormal twisting and without contact with adjacent parts.
• Periodically check the condition of the fastenings and the integrity of the safety cable.
