Shelf supports for Stack-On safe

These are shelf supports for a Stack-On GCB-900 safe. I've read some reviews of the shelves being weak and bowing/caving in over time due to weight on them, so I made these two simple supports as a fail safe.

Supports are 5.875" tall ( from bottom of unit to underside of first shelf, including foam bottom pad ), and 4.125" tall ( from top of bottom shelf to underside of top shelf ). The landings are 1.5" wide, and the parts are 6" deep.

My plan is to put them in the center of of the unit
