DF-192
★Product Introduction
DF-192 Button Chock is an essential basic hardware accessory in ship mooring systems. This product adopts an integrated casting process, with a compact and durable structure, specially designed for key positions such as ship decks and bulwarks. It is used to guide and limit the direction of cables, prevent direct friction, collision or strangulation between cables and ship structures. As an industry standard model, DF-192 is widely used in new ship construction, ship maintenance, port terminals, and offshore buoys, and is a core component to ensure mooring safety and extend cable life.

★Key Advantages
1. High strength integrated casting
The main body of the product is made of cast steel/iron, which is cast in one go without welding points. The structure is dense and has strong compressive and impact resistance. It can withstand high-strength tensile forces during ship mooring and is suitable for harsh marine conditions.
2. Super strong anti-corrosion performance
The surface is treated with black epoxy paint or hot-dip galvanizing, which has excellent resistance to salt spray and seawater corrosion, effectively resisting marine environmental erosion, greatly extending the product's service life, and reducing maintenance costs.
3. Compact and user-friendly design
The classic round head protruding design takes up minimal deck space and is easy to install; The rounded button style top design avoids cable bends and facilitates personnel's daily handling and operation, ensuring high safety.
4. Standard universal, easy to replace
DF-192 is an industry standard component with high standardization of size and interface, which can directly replace old or damaged parts. Installation does not require modification, greatly improving maintenance efficiency. It is the preferred spare part for ship owners, shipyards, and maintenance service providers.
