Our storage cutout covers are made from heavy duty vinyl coated mesh fabric.  The cover is attached to the boat using 4 snaps, one in each corner.  If you'd like 6 snaps, 4 in each corner with 1 in the middle top and bottom, please select that option.  Snap cap is black so you won't have to worry about glare.  The stud that the snap attaches to will have to be installed on your boat.  Due to the variance in cutout sizes, these are custom items, made to order.  We will need the height and width of the cutout on your boat.  Measure from the outside to outside.  If your hole has rubber trim, measure to the outside of the trim.  We add 1" to the left and right side to allow room to install studs.  If your cutout is 25" wide by 11" tall, you enter 25"x11" on your order and we'll send you a cover that is 27"x11".   If you would like 6 snaps, we will add 1" to the top and bottom to allow room for the middle snaps.  So if you enter 25"x11" and select 6 snaps, we will send you a 27"x13" cover.  Please allow 5 days from the date of order for your order to ship.  We cannot accept returns on custom size covers.
