BIG DIAMOND BOSS KIT is for real! Here’s the meat and potatoes .. We developed this for you as an aftermarket assembly system that encapsulates your boring old boss \[flange\] and converts it into a BIG DIAMOND barbell. This original, unique never seen before system is a man decoration made of stainless steel diamond tread plate and creates a modern structural product. This construction and final design has a limited capacity for fitment, so For you to own this we need for you to vernier caliper 3 measurements. As we receive your data we can now give you the custom internal parts you need to assembly and lock it on. The system screws together and mini rubber caps are back filled to keep screws from backing off. The design and materials here are sold to you with 100% satisfaction guarantee or money back and a lifetime warranty on construction.
