Spanner Wrenches

DWD Spanner Wrenches are used to assist with the installation of DWD Collars and Summo Series Poppets.  The inside of the "SQ-1" hole retains a standard square socket extension. 


Type "A" Spanner Wrenches slip into the pre-drilled holes on the face of the Collar or Poppet for normal installation and removal.

Type "B" Spanner Wrenches are specifically designed for the Summo-II Series poppet.  The Wrench has four drive dowels for easy installation.  If the Summo-II poppet has seized in the mold, the Spanner Wrench flips over and can be bolted directly into the drive holes for positive attachment.  Purchase of the CR-SUMMO2 Spanner Wrench includes (8) SHCS.
