LineTack Lights for flat surfaces are rubber spikes that stick to any flat surface to manage fly line. LineTack Lights can be used on the deck or cockpit of skiffs, boats, canoes, or paddleboards. The round EVA foam adhesive pads will remain in place under demanding condition, yet can be removed without damaging the surface. LineTack Lights form a barrier-fence that traps the line in a given area. The LineTack Light spike height: 3.875in. Each kit contains extra adhesive mounting pads for reapplication of LightTack Light spikes.
