I reached out to Grizzly and they don't have such an animal.
Thank you for your email dated May 9, 2016.
Unfortunately, none of our planers will accommodate 10” tall objects. There are no provisions available for modifying any of our planers to increase the cutting height, and we do not custom fabricate parts. A planer may break the box apart.
If we may be of any further assistance, please do not hesitate to contact us. You are a valued customer, and we look forward to serving your future woodworking and metalworking needs.
