Hi guys. I recently bought a Top Tier with 2 burners and a shelf tier. After I had everything installed, I got a screaming deal on a third burner. I'd like to have all three burners attached to the mast and use the shelf tier as an overgrown "utility shelf". I won't have a lot of weight on the shelf, most likely just a refractometer, thermometer, beer, and miscellaneous ingredients.
The Top Tier only comes with enough T-Slot Plates (the skinny plates that go into the mast) for installing three tiers. How could I install the shelf tier along with everything else? Is there somewhere I can buy additional T-Slot Plates? Would attaching the shelf using bolts and flat washers/nuts be strong enough?
