Grand Slam 300 Universal Backing Plate for GS-300 & GS-390 - Pair

The Grand Slam 300 Universal Backing Plate is designed exclusively for the innovative line of TACO Marine Grand Slam Outrigger Mounts – providing strength and directional guidance to your base when installed through your T-top. These unique backing plates feature directional markers every 22.5º, which align with the locking detents of the outrigger mounts as they are rotated and locked into position. This allows you to always know the position of your outrigger pole. Available in brite or black hard coat anodized finishes, these plates will save your T-top from potential damage caused by outrigger torque when extended.

Features & Benefits:

  • Provides strength, durability, and directional guidance 
  • Matches existing base hole pattern
  • No drilling
  • Attractive addition to your T-top
  • Sold in pairs
  • 5-year limited warranty

Specifications:

  • Backing plate, 6.50" X 5" X .25"
  • Finish: Brite Dip Anodized
