These need actual “force” to push together; they are not the “click” together kind. These can be installed with a rubber Mallet.
Installation: Place the male part on a wooden board. The male part is slightly smaller in width and will nestle within the female part. Place the female part on top of the male part and insert your setter. Give the setter a couple of hard taps with a hammer or until the male part is fully inserted and flush with the female part cap. To protect your grommets from being scratched, it is advisable to place a small piece of fleece between the grommet parts and the board and mallet
