NOTES FLAGS & GENERAL NOTES

    1. VERTICALS & PLANKS: NOMINAL 2×4 (ACTUAL 1 1/2" × 3 1/2"). RUNGS: NOMINAL 2×2 (ACTUAL 1 1/2" × 1 1/2"). ALL 96" STOCK.
    2. END LADDERS: RUNGS ON INWARD FACE ONLY. MIDDLE LADDERS: RUNGS BOTH FACES.
    3. BINS HANG BY THEIR MOLDED LIP ON A RUNG PAIR — ONE RUNG FROM EACH NEIGHBORING LADDER.
    4. ANCHOR TO WALL STUDS WITH ANGLE BRACKETS BEFORE LOADING. NOT A CLIMBING STRUCTURE.
    5. NO ENGINEERING SIGN-OFF IMPLIED — SCALES A PROVEN REFERENCE DESIGN, VERIFY YOUR OWN BUILD.

    APPENDIX ASSEMBLY INSTRUCTIONS

    LADDER TYPES

    THE SHELF IS 5 LADDERS STANDING SIDE BY SIDE, TIED BY 4 PLANKS. EACH LADDER = 2 VERTICALS (FRONT + BACK) JOINED BY 2×2 RUNGS RUNNING FRONT-TO-BACK. THE TWO OUTERMOST LADDERS ARE END LADDERS; EVERYTHING BETWEEN IS A MIDDLE LADDER. BUILD ALL LADDERS FLAT ON THE FLOOR BEFORE STANDING ANYTHING UP.

    END LADDER — BUILD 2 (SINGLE-SIDED, MIRRORED PAIR)

    1. LAY 2 VERTICALS ON EDGE, NARROW (1 1/2") FACE UP, ENDS FLUSH, SPACED SO OUTSIDE-TO-OUTSIDE = RUNG LENGTH (29").
    2. MARK EVERY RUNG CENTERLINE ON BOTH VERTICALS USING THE "MARK ON VERTICAL" COLUMN IN DETAIL B-1 BELOW — MEASURED FROM THE VERTICAL'S BOTTOM END. (THESE ARE THE SCHEDULE C FLOOR HEIGHTS MINUS THE 1 1/2" BOTTOM PLANK THAT SITS UNDER THE VERTICAL.)
    3. PLACE A RUNG ACROSS BOTH VERTICALS AT EACH CENTERLINE, ENDS FLUSH WITH THE VERTICALS' OUTER (FRONT/BACK) FACES. THE RUNG OVERLAPS EACH VERTICAL BY 3 1/2".
    4. FASTEN PER THE SCREW SCHEDULE BELOW. RUNGS GO ON ONE SIDE ONLY — THE SIDE THAT WILL FACE INWARD.
    5. BUILD THE SECOND END LADDER AS A MIRROR IMAGE SO ITS RUNGS ALSO FACE INWARD WHEN STOOD UP.

    MIDDLE LADDER — BUILD 3 (DOUBLE-SIDED)

    1. START EXACTLY LIKE AN END LADDER: RUNGS ON ONE FULL SIDE, ALL LEVELS, SAME CENTERLINE HEIGHTS.
    2. FLIP THE LADDER OVER. MARK THE SAME CENTERLINES ON THE SECOND SIDE — HEIGHTS MUST MATCH THE FIRST SIDE EXACTLY, A BIN RESTS ON ONE RUNG FROM EACH FACE.
    3. INSTALL THE SECOND-SIDE RUNGS. STAGGER THESE SCREWS 3/4" VERTICALLY FROM THE FIRST-SIDE SCREWS — BOTH SIDES DRIVE INTO THE SAME VERTICAL AND WILL COLLIDE IF ALIGNED.
    4. EVERY MIDDLE LADDER IS IDENTICAL — NO MIRRORING NEEDED.

    SCREW PLACEMENT SCHEDULE

    JOINTSCREWPER JOINTPLACEMENTTOTAL
    RUNG → VERTICAL, TOP + BOTTOM ROWS #10 × 2 1/2" 2 PER END (4/RUNG) DRIVE THROUGH THE RUNG'S SIDE INTO THE VERTICAL'S WIDE FACE, DIAGONAL PAIR CENTERED ON THE 3 1/2" OVERLAP. EXTRA SCREWS AT TOP/BOTTOM KEEP THE LADDER SQUARE. 64
    RUNG → VERTICAL, MIDDLE ROWS #10 × 2 1/2" 1 PER END (2/RUNG) SINGLE SCREW CENTERED ON THE OVERLAP AT EACH RUNG END. 48
    PLANK → VERTICAL #10 × 2 1/2" 2 PER VERTICAL, PER PLANK LEVEL PLANK LIES FLAT ACROSS THE VERTICALS' END GRAIN. DRIVE DOWN (UP FOR BOTTOM PLANKS) THROUGH THE PLANK FACE INTO EACH VERTICAL END, 3/4" IN FROM THE PLANK EDGES, ANGLED SLIGHTLY (~5°) FOR END-GRAIN BITE. 40
    ANGLE BRACKET → TOP PLANK #14 × 1 1/4" 4 PER BRACKET BRACKET ON TOP OF THE REAR TOP PLANK, VERTICAL LEG AGAINST THE WALL. FILL ALL 4 PLANK-SIDE HOLES. 8
    ANGLE BRACKET → WALL STUD #10 × 2 1/2" 4 PER BRACKET EVERY WALL-SIDE SCREW MUST HIT A STUD — LOCATE STUDS FIRST AND POSITION BRACKETS OVER THEM. DRYWALL ANCHORS ARE NOT ACCEPTABLE. 8

    GENERAL FASTENING NOTES

    1. PILOT-DRILL EVERY 2×2 RUNG HOLE 1/8" — 2×2 STOCK SPLITS EASILY NEAR ENDS. KEEP SCREWS ≥ 3/4" FROM ANY RUNG END.
    2. ASSEMBLY ORDER: BUILD ALL LADDERS → STAND END LADDER + FIRST MIDDLE LADDER → ATTACH BOTTOM PLANKS → ADD REMAINING LADDERS → TOP PLANKS → CHECK DIAGONALS FOR SQUARE → ANCHOR TO WALL.
    3. SPACE LADDERS USING A BIN AS A GAUGE: DROP A BIN BETWEEN LADDERS BEFORE FINAL PLANK SCREWS — IT SHOULD SLIDE FREELY WITH THE LIP RESTING ON BOTH RUNGS.
    4. SNUG SCREWS FLUSH; DO NOT OVERDRIVE INTO 2×2 RUNGS.
