The Coaming Pad Hook & Eye Set is installed on the back side of your coaming/bolster pads to fasten them to your boat's substrate. This coaming pad hook and eye set (clip) is a two-part design made of high-quality Type 316 stainless steel. Due to the low-profile design, the clip does not require large mounting holes in a bolster/coaming pad's backer board or the boat's substrate. Clips are sold as a set and include both components to make for easy upholstery installation and removal.
