Set of 2 Anti Slam locks for seitz midi heki to prevent roof light lifting and slamming closed in wind causing expensive damage. This lock is only suitable for the midi heki and will not fit other models. This is a 3d printed item in white. If you are not familiar with the 3d printing process the item will show small layer lines on the surface and may show small imperfections but this will not affect the structural integrity of the item. And questions feel free to ask and I will try my best to answer thanks for viewing I also sell maximum hight locks to lock the vent at its maximum hight in my listed items
