MAXIMIZING LOWERING OF OBJECT
You may want to lower object to floor or onto sawhorses.
If distance 2 is much greater than 3, the distance object
can be lowered will be limited by length of rope supplied.
Drill a 7 /
32
" (5.5 mm) hole into top plate of garage for mounting
welded screw eye. Always wear safety glasses. Screw welded
screw eye into top plate until threads just disappear into top
plate. Do not overtighten. See procedure and warnings for
Install Pigtail Lag Screws.
Mount 2" x 6" x 7" (50 mm x 152 mm x 180 mm) riser
board on front mounting board centered between the
two pigtail lag screws (B). Drill
5 /
32
" (4 mm) holes.
Always wear safety glasses. Attach riser boards using
two
1 /
4
" (6 mm) lag bolts (l) and washers (J) (included).
Do not overtighten.
DIAGRAM 8. Hold rope organizer plate (K) on riser board near
the side toward the front wall. Use plate as template to mark
center holes. Drill two 5/32" (4 mm) holes.
