Frequently Asked Questions (FAQ)
-
Q: What is the maximum load capacity of this 4-way arm?
A: The exact load capacity depends on the installation angle and glass thickness. Typically, our 304 stainless steel 150mm arm can support static loads up to 1500 kg (tested). Please contact us for detailed technical data and project-specific calculations. -
Q: Is the arm compatible with curved glass?
A: Yes, the 4-way arm can be used with curved glass panels if the curvature angle is within the adjustable range of the spider. Customized arm lengths are also available for special geometries. -
Q: What is the difference between 304 and 316 stainless steel?
