3.  Category I bracket 
The SeaShelter
3
™ Category I bracket has five pre-drilled screw holes to use 
for securing the bracket to a flat surface. Remove the SeaShelter
3
™ lid by 
turning the spring loaded knob on the lid 1/4 turn counterclockwise and pull. 
The lid will lift away from the top of the base and disengage at the bottom of 
the  base. The  lid  is tethered  to the  base  to help  prevent  loss. Pull  the 
beacon with steady pressure from the bracket. It is not necessary to remove 
the HydroFix™ Hydrostatic Release Unit (HRU) to mount the bracket using 
four of the holes. For extreme conditions a fifth hole is available when the 
HydroFix is removed and the ejector spring is deployed. The bracket can be 
held in place to mark the placement of the screw holes or you can use the 
mounting  template  provided.  The  use  of  #10  pan  head  stainless  steel 
fasteners  (minimum  of  ½”  long)  and  ½”  washers  (not  included)  is 
recommended.  Make  sure  that  fasteners  will  not  contact  any  wires  or 
plumbing before drilling pilot holes.
