These brass caps and chains are used on fire department connections, hydrants, valves, etc. and feature a pin lug design in solid brass. The 2.5" size refers to the hose line diameter, not the fitting diameter; the vast majority of FDC's are for 2.5" hoses.
This item is available in your choice of regular brass, polished brass, or chrome-plated brass. The regular cast style is available made in USA for a premium price or made offshore for an affordable price; yes, it's sad, we know. (By the way did you know that the majority of our items are made in the US, including our full Chemglass, Eagle, Guardian, Wilrary lines and most of our labels and signs, too?).
Due to daily fluctuations in metal prices, the price shown here is subject to change without notice; in the event of an unexpected price increase we will confirm the new price with you before filling your order, of course. It the price of brass caps gives you sticker shock, some less expensive solutions are our aluminum break caps, item # 09204, or our plastic ones, item # 09207 and 09208.
