Beer Can Chicken Grate

I recently saw on the BBQ Bootcamp show that the couple from Alabama (?) had a grate for Beer Can Chicken which had 2 sleeves to hold beer cans. Where can I find one of those?!?

They are sold at our local sporting goods chain - Academy Sporting Goods

Cabela's sells a single for $9.99, a double for $14.99 and a stainless steel double for
$19.99.
