The GP125 dual-stage locking padlock seals are among the most reliable and durable security seals used in the transportation industry. These seals are widely used to prevent cargo from being opened during transport. This is because the dual-stage locking padlock seal features two distinct locking mechanisms. The first locking mechanism engages automatically when the seal is closed, while the second locking mechanism is activated manually and ensures the seal is even more secure.
Furthermore, just like all security seals produced under the Gökerplast brand, these lockable seals fall under the category of meter seals and are considered a critical component, particularly for the transportation industry. Moreover, at Gökerplast, we ensure that all our products undergo RoHS compliance testing, as well as TSE tensile and UV resistance tests.
For further details, please refer to the product specifications table.
The GP125 is made of an ultraviolet resistant Polycarbonate (PC) body and a Polyacetal (POM) interior.
The inner part is mounted in the housing to prevent tampering from the outside.
There is a flag option (GP125-L) for use with barcode.
The transparent body can be printed with a white background that is resistant to all solvents to improve barcode reading quality.
Both the body and the inner part are laser engraved with a serial number.
RoHS (Restriction of Hazardous Substances) Directive 2015/863 compliance report is available.
UV resistance test available according to ISO 4892:3.
Tensile Strength 15 Kgf
Operating Temperature: -40°C / +120°C
The inner part is mounted in the housing, making tampering from the outside difficult; the transparent PC housing makes tamper marks instantly visible and enables quick inspection in the field.
The serial number, laser-printed on both the body and the inner part, guarantees component matching, reduces the risk of duplication and facilitates batch tracing.
Offers flag option for use with barcode. Solvent resistant white background applied on transparent body provides fast/clean reading with handheld terminal and camera.
UV-resistant Polycarbonate (PC) body and Polyacetal (POM) mechanism provide stable performance in outdoor environment, preserve color/transparency and ensure long-lasting use.
