I’ve wanted power tool storage in my 56” series 2 box for a while. I almost bought the 56” Icon but decided it was sort of crazy to spend an extra $1400 over one drawer. HF finally came out with their accessory for the drawer but didn’t say if it was backwards compatible and I believe the series 3 drawer is different. Luckily it fits great and I finally have my power tool storage. Overall quality is a bit cheap. It’s $25 with the club discount and I would gladly pay double or triple for a more solid and high quality piece - but it is what it is. Here’s a couple pics to show fit. I use the accessory tray on the side for easy access but it’s nice to have accessible storage inside the box.
