An automatic door closer kit for a sliding door assembly comprising a doorway having first and second vertical jambs, said jambs being horizontally spaced, an upper horizontal lintel connecting across said jambs and having two downwardly extending parallel rails, said doorway frame defining a vertical plane, a stationary panel mounted within said plane adjacent said second jamb, a movable rectangular door having an upper leaf, a lower leaf, first and second vertical stiles with said first stile being adjacent said first jamb when said movable door is in a closed position, the upper leaf of said movable door being received within said rails of said lintel so that said door is slidably mounted within said plane of said doorway frame;

• said door closer kit being gravity actuated and comprising;
• a counterbalance having an adjustable weight capacity,
• an anchor pulley mechanism including a first L-shaped base having a first outwardly extending post mounted on the inside of the L, a grooved anchor pulley wheel rotatably mounted on said first post, double-faced adhesive tape mounted on the outer surfaces of said first base for attachment of said first base to one of said rails and to said lintel,
• a traveling pulley mechanism including a second L-shaped base having a second outwardly extending post mounted on the outside of the L, a grooved traveling pulley wheel rotatably mounted on said second post, double-faced adhesive tape mounted on the inner surfaces of said second base for attachment of said second base to said second stile;
• a lifting pulley mechanism including a third base in the form of a four-sided box, a third post extending outwardly from the outer side surface of one of the sides of said box, a grooved lifting pulley wheel rotatably mounted on said third post, double-faced adhesive tape mounted on the outer surfaces of the other three sides of said third base for attachment of said third base to said second jamb, to said lintel and to said frame, and
• a cord having one end thereof attached to said counterbalance, said cord being entrained over said lifting pulley then about said anchor pulley and about said traveling pulley, the other end of said cord being secured to said first base.
