Details of 124 Type Galvanized Key Clamp Fitting:
Introduction:
124 Elbow is a special type of Key Clamp fittings, it is designed for the guardrail system when the angle between the uprights and the handrail is between 125° and 178°. Later, it was extended to the guardrail system to connect two rails at an angle to each other, as well as many DIY structures.
Handrail:
Handrail system with an inclination angle of 25° to 80°: used to connect the uprights below and the upward handrail pipe. Such as wheelchair access, home stairs, climbing guardrails, etc.
Guardrail:
When an angled site needs to be enclosed, the 124 Type Galvanized Key Clamp Fitting can be used to connect two rails with an angle between 125° and 178°. Such as seaside guardrails, platform guardrails, roofs, etc.
DIY Structure:
It can be used to build outdoor recreational facilities and fitness facilities. Indoor furnishings, brackets, tables and chairs, etc.
124 Type Galvanized Key Clamp Fitting structure and installation:
Structure:
It has two sockets, each with an Allen Bolt. The middle part has a larger inner cavity, so that the pipe can adjust its angle inside, and the mouths of the two sockets fit the outer diameter of the pipe.
Installation
Important Note:
In most cases, it can only be used in a system under construction. If it needs to be installed in a completed system, the feasibility of this idea needs to be carefully considered.
How it Work:
1. Insert one end of the two pipes into the 124 Type Galvanized Key Clamp Fitting,
2. Adjust the angle of the pipes and insert the other end into the sockets of other Key Clamp Fittings,
3. Slowly push the two pipes to fully insert the Key Clamp Fittings,
4. Use the Allen Key to tighten the four Allen Bolts (two on the 124 Type Fitting and one on each of the other Key Clamp Fittings).
Surface Treatment:
124 Type Galvanized Key Clamp Fittings mainly have three types: Double Coating, Hot-dip Galvanizing, and Powder Coating. Some customers also purchase raw black (without any surface treatment). We should consider the use environment of Key Clamp Fittings in specific projects. For example, in a chemical plant, we need to consider the pH of the environment and whether it will react with the surface of the Key Clamp Fittings.
Material & Production of Key Clamp Fittings:
The material of its body is:
Cast iron, the common ductile iron and malleable cast iron, the performance of the two materials is similar in most cases. The performance standard of Key Clamp Fittings needs to consider its usage scenario.
The material of Allen Bolts:
It is stainless steel, which has strong rust resistance and fastening ability.
Production of Key Clamp Fittings
Its body is made of sand casting, finished and galvanized.
