The 1/4" BF safe Okay, here is the deal. The heavy liner BF is not in the lineup for next season. However, if you want one, call your local dealer/distributor and ask for a quote for a BF with a 4-gauge liner. Our manufacturing and engineering is GTG, but we shelved the product for the time being. However, I am told we will take orders for custom make-to-order BFs with a 4 gauge liner. The price should not be outrageous. Our team is expecting inquiries, so if you want this, there is a good chance you can get it done.
