Quickly, easily and precisely trim bullnose edges on deck castings.


  • Dramatically reduces previously time-consuming finishing process with better result.
  • Follows contours of top surface for uniform bullnose profile across entire length.
  • Prevents narrowing when used on bowed or warped decks.
  • Two versions - 120V (for U.S.) or 220V.

This system simplifies trimming of bullnose edges on decks of all sizes, and produces straight, machine cuts that minimize labor costs for this operation. An optional 8’ trim table properly positions the deck edges for cutting. The top edge is easily replaceable wood if excessive number of blade cuts destroy the original.

Using it is simple. Set the deck on the trim table, with the bullnose edges hanging over. Position the saw with the guide attachment on the deck surface, and trim the excess bullnose edge flash material off along an entire surface. Repeat on each side.

The finished deck requires minimal cleanup afterwards with a simple sanding block to smooth any remaining protrusions.

The saw (with integral guide) is positioned for the cut by placing the saw on the front edge of the bullnose contour. The guide ensures that the saw is positioned properly, and that the resulting cut will be uniform along the entire run.
