Todd, Wouldn't worry too much about the head guard. Fork lifts or pallet loads handled by a fork lift would just wrap the guard around the broken head.
The obstruction issue is not as easy. A 20 ft. ESFR should not be necessary for 8-9 ft. of storage under a duct. I know it's not technically correct but I would put some 1/2" heads under the duct. There is another approach I have always wanted to try. What if the duct were wrapped in a combustible carton of some sort with wood pallets strapped to the underside? Wouldn't it be like multi-row rack storage and not require heads beneath?

The duct is about 8-9 feet off the floor in the 20 ft warehouse. My plan is to install 3 ESFR sprinklers below the duct. The question I have is about protection of the sprinkler and obstructions. I'm assuming that installing a sprinkler guard per 6.2.8 (2002) in not allowed. What other options are out there? This space is occupied by some palletized storage and forklift parking, so damage is a possibility. My original thought was upright ESFRs on sprigs, but that may not work in this case. Thoughts?
