Custom Aluminum Frames Style No 5

Thank you for contacting us. This frame style has a channel rabbet that your artwork must fit within. The depth of the channel is 13/32" which is just over 3/8". You cannot frame a 1/2" depth canvas with this frame. The frame depth is too large to fit within the channel. You could use style 22 which has a channel depth of 1" inch https://www.jerrysartarama.com/framing/custom-frames/custom-metal-frames/custom-aluminum-frames-style-no-22 I would caution you to not use an aluminum frame because the inner edge of the frame can dig into the front edge of your canvas around the edge of the stretcher bar. https://www.jerrysartarama.com/media/catalog/product/cache/1/image/600x/040ec09b1e35df139433887a97daa66f/0/0/0047017gol000-st-05-metal-sectional-frames-rabbets.1535730057.jpg
