Bronze Spanner Wrench and Deck Plate Key
This adjustable spanner wrench serves strainer caps or deck plates with key holes up to 7" apart. Specifically designed to fit the strainer cap for most Groco strainers (ARG, SS, SD, and BVS series), use it as a spanner wrench to tighten or loosen the cap before or after maintenance.
Hand tight is sufficient for a good seal for GROCO strainers with threaded caps, but some boaters may prefer to "snug" the cover beyond hand tight.
Note: Do not use to tighten non-metallic caps.
