Without the bezel...
I got the bezel from
AmericanFrame.com.
Here are the details12-1/2"W x 9-1/2"H (18301) Bravo, Matte Black
(Artwork Size: 12-1/2"W x 9-1/2"H) -- ASSEMBLE FRAME --
Quantity: 1 Item Price: $27.55
I needed to remove some material from the back of the bezel. I temporarily attached some guides.
...used a straight router bit and collar...
...and took many shallow passes...
I used weather stripping to fill the gap between the frame and the glass
Here it is with the velcro ready to install.
