DECK PLATE KEY /SPANNER WRENCH

• Among the features of ARG, SS, SD and BVS series strainers are provisions on the strainer cap for the use of a spanner wrench to loosen the cap before or after maintenance. Hand-tight is a sufficient seal for GROCO  strainers with threaded caps, but some boaters may prefer to "snug" the cover beyond hand-tight. NOTE: Do not use SW-2531 to tighten non-metallic caps.
• Cast bronze with stainless steel pins to fit 1/4" and 5/16" holes.
• Opens to service deck plates or strainer caps with key holes up to 7" apart.
• Hangs conveniently near the strainer(s) location.
