This Sierra Brand Hose Ladder Strap is used to hook a charged fire hose on to an extended ladder. The strap is wrapped around a hose, then hooked on one of the ladder rungs to keep the hose from slipping off. "Sierra" is stamped on the hook. Strap is 34" long.I have no idea how old this is, but I have had it for over 40 years. This rare ladder strap tool is in excellent ready-to-be-used conditon and anxious for the next fire, or for proud display in your fire memorabilia case. I have been in the fire EMS service since the 60s and I have a lot to sell. Check out my other listings. Thanks for looking and Good Luck. Jim Paypal payments only please.
