What Is a Catch Clip?
A catch clip, also known as a snap lock or tailstock, is a stainless steel clip that is attached to a catch clip-type sealed container and is also intended to lock the lid.
The hook portion of the catch clip is hooked over the rim of the lid, and the lid is secured by lowering the lever to allow simple sealing.
Since it is welded to the body of the container, there is no need to worry about losing the fixture during storage compared to a lever band.
Uses of Catch Clips
Catch clips are used on the lids of toolboxes, toolboxes, and attaché cases, where they are used as hinges and closures.
There are various types of catch clips for different applications.
Even the standard type comes in a variety of sizes.
The catch clips with a metal fittings insertion type have a metal fitting inserted into the body.
The type for protruding objects can be clamped with metal fittings while avoiding protruding parts of the box.
Spring-loaded type can absorb vibration by spring action.
The cylinder lockable type can be padlocked.
Lockable types can be managed with a key.
Latch type prevents the latch from disengaging due to vibration.
Principle of Catch Clips
The mechanism of catch clips is the hook is pulled by a spring force to hold it in place.
The key point here is that there is a slight difference in height between the center of the hook of the catch clips and the fulcrum of the handle.
The side of the handle is slightly higher than the other side so that a slight downward force is applied to keep the handle from lifting off the ground.
If this were horizontal, the handle would be in an unstable position and would not be able to serve as a lock.
Thus, the catch clips allow the lid to be tightened by the action of a spring.
Some catch clips are made of cold-rolled stainless steel sheet (SUS304), and being made of stainless steel, they are extremely resistant to corrosion.
Some have a barrel-polished surface finish.
