Wow!!!! I'm really surprised at the remarks and the question. Been fabricating, (cutting, welding, assembling), starting in 1965 and always, always had access to at least (3). Built my (2) car in '95 to build my '34. Garage is unusual in that its 45' x 16 so and the FE's to me were as essential as the doors. In fact the (3), are located, one at the big door, one in the center and one at the work bench were installed before any thing else was. These are the largest Home Depot sells also. Iv'e seem fire in a shop, putting out one myself when a acetylene bottle valve, at the bottle went off at the valve. Scary stuff.
