Anvil International introduces a new 1” SlideLOK technology 74FP coupling to its SuperFlex flexible sprinkler drop assembly for faster and easier fire-sprinkler installations. The SuperFlex SLT/74FP integrated coupling eliminates sprinkler positioning problems due to ceiling sag or shift, the company notes. Used with standard 1” groove Weld O Lets and fittings, the SLT coupling eliminates the need for cutting tools, taping or doping of threaded fittings, and on-the-job custom armover fabrication. Anvil’s SuperFlex hose/coupling assembly is the only fully welded flexible sprinkler drop in the industry, the company adds.
