TACO Wedge Plate f/GS-850 & GS-950

The TACO Wedge Plate for GS-850 & GS-950 is a precision mounting correction accessory designed to align Grand Slam antenna mounts and light fixtures perpendicular to curved T-top surfaces. Marine installations rarely feature perfectly flat mounting surfaces, and even slight curvature causes misalignment that degrades both functionality and aesthetics. This plastic wedge plate solves that problem by shimming the mount angle to true vertical, maintaining the professional appearance of your Grand Slam 850 Electric VHF Antenna Mount and Grand Slam 950 Electric Anchor & Stern Light installations.

Measuring 4 x 1 x 4 inches and weighing just 0.25 pounds, the wedge plate integrates seamlessly into the mounting footprint without adding bulk or weight penalty. The design compensates for angular inconsistencies that would otherwise force installers to accept crooked mounts or over-tighten fasteners—both of which compromise structural integrity over time. By restoring perpendicular alignment, the wedge plate ensures even load distribution and protects antenna performance, particularly critical for VHF communication reliability and proper light beam orientation on the water.

This accessory is essential for custom boat builds, retrofit projects, and any installation where T-top geometry doesn't match mounting assumptions. Serious anglers upgrading electronics and weekend boaters installing safety lighting both encounter this challenge. The TACO wedge plate (part number WP-850-950) is the OEM solution—purpose-engineered by the manufacturer to work specifically with these two Grand Slam models rather than relying on generic shimming or improvised workarounds that may shift or deteriorate under marine conditions.
