These aluminum break caps keep dirt, debris and animals out of fire department connections, hydrants etc. They are an economical alternative to brass caps, and are easily broken with a hydrant/spanner wrench. These use eye bolts to secure the cap via the inlet’s pin lugs. Available in unfinished aluminum or red. Sold in sets of two complete with eye bolts.
Note: Most FDC's are 2.5", which refers to the diameter of the fire hose, not the diameter of the connection. The outside diameter of these caps is 3.5", the outside diameter of their inner ring is just under 2.75", and the lug connection holes are 4" apart.
