I would have to agree with 7TSS statement. The one thing I would do is shoot myself in the foot with a 10-15% increase. What I would do is offer the hinge with the black strut and use the SS strut as a product upgrade. Give the potential customer the choice on the setup of your product.
I’m not really new to the page I just haven’t posted much so not sure if my opinion counts but will say it anyway.
