ACXFOND 6061-T6 Aluminum Sheet 8x12x1/2 Inch Thickness Durable Aluminum Plate, Thick Metal Aluminum Sheet Covered with Protective Film for Industry, DIY

I didnt have spend time looking for it.

Watch for the edges though they are Sharp as they are cut square without being deburred which would round the corners. In my opinion that is a good thing as you may be needing it to sit flush against something else that is flat.

This plate has 90.0 degree corners, both surfaces flat and well protected, and at a great price. If you need a 1/2 inch plate you can order this with no worries, I highly recommend. What would make it even better is if they offered a 12x12 plate, that would be awesome.

Item as described. Suited my needs to use for a support plate on a trolling motor. Unbelievably cheap.
