Q: How does the friction-based design ensure smooth operation?
A: The friction between the plastic components of the door stay eliminates any abnormal sounds and ensures smooth movement during door operation.

Q: Can I adjust the door’s stopping position?
A: Yes, the torque of the stopper can be adjusted to stop the door at your desired position, providing precise control over door movement.

Q: Are the torque variations affected by temperature changes?
A: No, our One-Way Torque Door Stays have minimal torque variations due to temperature changes, ensuring consistent performance in different environments.

Q: What materials are used in the construction of the door stays?
A: The arm/main body of the door stays is made of stainless steel plate (SUS304), while the case is made of polyacetals (POM), ensuring durability and reliability.

Q: Is there anything I should be cautious about when using these door stays?
A: To avoid any potential dangers, it is important to set the torque to a low setting. It is also advised not to exceed the torque adjusting range of 78N to prevent idling or incorrect functioning by the gear. Lubricants should not be used with these door stays.
