I have some wood chip trays for sale. At this time, I have 7 of them available. 69mm barrel length, overall size is 8-1/2 L"x3-1/8" W x1-7/8" H. Solid maple. Milled to fit 44mm chips, 4 rows each to hold 80 chips in total. These are hollow underneath so that they will stack on top of regular racks of chips. $30 USD each plus shipping. I have more that are being finished up which are 70mm barrel length. Next up on the block: 39mm wood chip trays, also solid maple. These hold 100 chips each, barrel length is 68.5mm. Overall size is 9-3/4" L x 3-1/8" W x 1-7/8" H. 11 available. $25 USD each plus shipping. More available soon. These are milled underneath as well so the racks will stack on top of each other without sliding around. They will not stack on top of plastic racks though since each row is spaced apart further.
