Often found on boat covers to firmly attach a cover or hood to the hull. The attachment has a nice firm feel to the snap on and off and is robustly built. The fixing locks on three sides and can only be released when the fourth side is lifted from the attachment. Available in various fittings, make sure you choose the best style for your needs from the drop down, so that the pack has the correct backing for your use. Sold with 5 fixings per pack.
