Friction stays are an essential component of many industrial and commercial applications, acting as the gatekeepers of heavy doors, hatches, and covers. They play a pivotal role in ensuring safety, reliability, and ease of operation. Choosing the right size and strength of friction stays is crucial to maximize performance and prevent costly failures.

Determining Size:

1. Measure the Size of the Opening: Determine the height and width of the opening that the friction stay will support.

2. Consider the Type of Door or Cover: Different types of doors and covers have varying weights and thicknesses, which impact the required size of the stay.

Calculating Strength:

1. Estimate the Weight of the Door or Cover: Accurately determine the weight of the door or cover to be supported.

2. Determine the Required Hold Force: The hold force is the amount of force required to keep the door or cover in its desired position. It should be slightly higher than the weight of the door or cover.

3. Calculate the Arm Ratio: The arm ratio is the distance between the mounting point of the stay and the point of resistance. A higher arm ratio increases the lifting capacity of the stay.

Selecting the Right Stay:

1. Choose the Correct Arm Length: Select a stay with an arm length that matches the dimensions of the opening.

2. Ensure Adequate Hold Force: Verify that the hold force of the stay meets or exceeds the required hold force for the application.

3. Check the Arm Ratio: Choose a stay with an appropriate arm ratio to provide sufficient lifting capacity.

4. Consider Mounting Options: Determine the mounting method (e.g., surface mount, recessed mount) required for the specific application.

Other Considerations:

Temperature Range: Ensure that the stay operates within the expected temperature range of the environment.

Corrosion Resistance: Select a stay with appropriate corrosion resistance for the application conditions.

Safety Features: Consider stays with safety features such as automatic locking mechanisms or overload protection devices.

Choosing the right size and strength of heavy-duty friction stays is essential for optimal performance and safety. By following these tips, you can ensure that your friction stays provide reliable and effortless operation in demanding industrial and commercial environments.
