The rails are bolt-in so it mounts into the factory bolt holes. Sliders allow you to move forward and backwards. The brackets have slotted holes for reclinability and height adjustment.
D-Lock is for Double Locking. Rails lock on both sides for added security.
Will fit most standard size side mount bucket seats.
