Measuring a cam lock fitting correctly depends on whether you are measuring an adapter (male end) or a coupler (female end), as they require different measurement points to determine their size.
Measuring Cam Lock Fittings
To accurately measure a cam lock fitting and determine its size, follow the specific methods for adapters and couplers:
Measuring an Adapter (Male End)
According to the provided reference, to obtain the proper size of the adapter, you would measure from one outside edge to the other outside edge of the adapter. This measurement provides the nominal size of the male fitting.
- Method: Use a caliper or measuring tape.
- Location: Measure across the widest part of the adapter head, from the outer edge on one side to the outer edge on the opposite side.
- Purpose: This measurement helps identify the correct size of the adapter that will fit into a corresponding coupler.
Measuring a Coupler (Female End)
For the female end of a cam lock fitting: To obtain the proper size of the coupler, you would measure from one inside edge to the other inside edge of the coupler. This measurement corresponds to the Inside Diameter (ID) of the coupler. As the reference states, female camlock sizes are referred to by their inside diameter or ID.
- Method: Use a caliper or measuring tool.
- Location: Measure the internal diameter of the coupler opening, from the inner edge on one side to the inner edge on the opposite side.
- Purpose: This measurement ensures the coupler can properly receive an adapter of the corresponding size.
Summary of Measurement Methods
Here’s a quick summary based on the measurement points:
| Fitting Type | Measurement Location | What it Determines |
|---|---|---|
| Adapter | Outside Edge to Outside Edge | Nominal Size |
| Coupler | Inside Edge to Inside Edge | Inside Diameter (ID) |
By following these specific measurement techniques for adapters and couplers, you can accurately identify the size of your cam lock fittings, ensuring proper compatibility and a secure connection.
