Spanner Wrench

Spanner Wrench


Caps for ARG, SS, SD and BVS series strainers have holes for the use of a spanner wrench to loosen the cap before or after maintenance.   Hand-tight produces 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. 
              • C83600 bronze.
