Fire Snap Hook DIN 5299

The DIN 5299 snap hook is a component for attaching items to ring brackets, chains, or wire ropes. Once installed, it forms a quick-release connection resistant to mechanical load.

Design features

A snap hook is a quick-release connector with a spring-loaded or screw locking mechanism. In the spring-loaded version, the element preventing the chain or bracket from slipping out returns to its initial position automatically. The screw mechanism protects the snap hook from accidental opening. The normal position of the gate is closed.

Regulatory documentation

Snap hooks are manufactured according to the process set out in DIN 5299. The characteristics of a snap hook depend on its overall dimensions.

Application

A snap hook is installed to connect a rope or chain to the required object when a quick-release connection is needed within a short time. This makes it useful for temporary couplings. The DIN 5299 snap hook is used for:

• rigging work;
• installation work;
• assembling fall-protection equipment;
• work at height;
• towing light vehicles.

When selecting a DIN 5299 snap hook, its characteristics must be taken into account. Exceeding the permissible values will cause the part to fail.

Advantages of the snap hook

1. Resistance to mechanical load. Snap hooks are made of carbon steel, as required by the regulatory documents. A zinc coating is applied to the surface to protect the metal from corrosion.
2. Easy installation without specialized knowledge or skills.
3. Reliable attachment: the locking element prevents the bracket, chain, or wire rope from slipping out accidentally.

When selecting a snap hook, the permissible load is taken into account — this ensures a secure temporary connection that reliably holds the object on the wire rope.
