To hang the record on the wall, align center on the hanger and lightly pull down to secure into the tapered slot. This will prevent the record from rotating aswell.  added benefit is that it is spaced away from the wall so there is no risk of the reverse side getting scratched or damaged from the wall. Reccomend using Wire brad nails to secure to the wall and using a marker to cover the head once installed. This wall hanger uses less than 7 grams of filament to print.
