The Carrier gives added versatility to your gear. When working inside, you don't want to chance your rig banging into a new cabinet or door. Now you can take your same pouches inside with the Tool Carrier. Pouches, pockets and tool holders can all be attached to the Carrier. Since there are no exposed rivets on Iron Dog you don't need to worry about scratching a surface.
The Carrier can also open up to fit over a ladder, sawhorse or a railing. This keeps everything you need right at hand.
