One of my favorites and most versatile tools on the fireground:
A Message from Bob Farrell Captain, FDNY and CEO of Fire Hooks Unlimited We are the original developers of the New York Roof Hook. If it doesn't say "Fire Hooks Unlimited" - aka "FARRELL HOOK" on the head, it is a copycat product not meeting the spec's of the Fire Department City of New York (FDNY). Our hook has been around for over 25 years of successful service as the "official" hook of the FDNY.
Developed by the experience of over 20 years of service in the busiest fire houses in the FDNY, if not the world, during the 1960's and 1970's (the War Years). We participated in the development of this tool with the New York City Fire Department - Research and Development Division.
Our all-purpose head, aircraft steel shaft, chisel end, and celtex grips makes up this unit. The chisel end is used as a prying tool for scuttle hatches and roof doors. The short lengths are good for going up fire escapes and scuttles to the roof. Accept only aircraft steel for lightweight, but strong tool.
