These strong straps...Northwest River Supply, are perfect to keep your cooler secure and latch closed. I will cut the extra in half (6' strap) leaving about 10" to pull tight in buckle and tuck behind. Screws show on top and front...there are two more screws securing strap to middle of back and bottom. Placement allows cooler to fully open. AND...TSA can't "lose" your strap and let your cooler come open! #8 pan head sheet metal screws with #8 flathead washers.
