Thank you! Is this what is called a flanged edge? Is that just strips of acrylic that they attach to the outside of the box?Welcome back.
Here you go...
Dimensions of the edge strips are typically 1/4" wide, to fit under the frame's lip, and 3/8" to 1/2" high, to fit the rabbet depth of the frame.
I normally specify black edge strips, because they are less conspicuous under the frame's lip than clear edges.
I think these are held in place with fitting points like a more traditional frame. The back of the acrylic box with the flange would provide the rabbet. No need to screw the box to a strainer insert as with acrylic boxes without frames.Also, where are the screw holes to attach the box to the base? Thanks!!!
Thank you so much!
