This is a bin and bracket system that mounts under your various InLine Fabrication toolhead docks. (Dillon, Redding, Lyman, RCBS ) It allows you to keep all your caliber components & misc parts/pieces in one place and also offers up a little extra secure storage space that we all could surely use. Bracket also has stops built in on the edges to prevent the bin from being knocked off the side by accident.
Also works with the Factory Dillon toolhead stand (Here)
Includes bin, bracket and mounting hardware. (Does not include bin barrier) Those are available (Here)
