There are two designs one holds 8 sticks of ram the other holds 16.
See images for dimensions, the trays are just slightly wider than the ram, and a bit shorter so you can easily remove the sticks of ram.
The 4 and 8 stick racks come with press fit lids, the lids don't fit all ram types as ram with heat shields can be unpredictable in height. If you'd like a custom lid let me know.
