(No reviews yet) Write a Review

The anchor incorporates a revolutionary swivel ring design that allows a D-ring to rotate 360 degrees as well as flip back and forth at 180 degrees. The Swivel Anchor’s incredible strength is due to a heavy gauge heat treated alloy steel, reinforced bridge, D-ring, and locking caps. Its patent pending key lock design keeps the D-ring seated and locked into its swivel housing, preventing the steel from spreading outward during heavy loads.

The Weld Puck Kit is a weld on mount for Frontline’s 10K Swivel Steel Anchors. The anchor is of mild carbon steel and a grade 8 5/8″-11 bolt and internal lock washer are included in the kit.
