I. Insert the Selector Stem into the weight stack while holding the Selector
Stem several holes above the Top Weight. Insert the Weight Pin, suspending
the Selector Stem. Place the cylindrical clevis end of the cable over the
Selector Stem and raise the Top Weight so that the holes in the Top Weight,
Selector Stem and clevis align. Attach using 1 – 3/8” x 1 ½” cap bolt.
J. Install a 4 ½” pulley under the cable and insert the pulley between the plates
of the Loop Upright. Attach using 1 – 3/8” x 1 ¾” bolt, 2 – 3/8” flat washers,
and 1 – 3/8” nut.
K. Route the cable down between the plates welded to the base of the Loop
Upright. Install a 4 ½” pulley over the cable and attach to the plates using 1 –
3/8” x 2” bolt, 2 – 3/8” flat washers, and 1 – 3/8” nut.

MEC ASSEMBLY INSTRUCTIONS
CABLE ADJUSTMENT
T. Once the Multi-Leg Extension/Leg Curl is completely assembled, loosen bolt
that attaches pulley and Guide Rod Bracket to the Loop Upright (installed at
step H.). Raise or lower the bolt and pulley to remove slack from the cables.
Make sure that the Weight Pin still engages all weight plates with the Selector
Stem. Once the cable tension is correct, rotate the Cam Washer so it rests
against the triangle support and re-tighten bolt.
PLACARDS AND LABELS
U. Remove backing from foam tape on Instruction Placard. Attach Instruction
Placards to Loop Upright aligning outside edge of placard to top and outside
edge of Loop Upright.
V. Attach Weight Labels in recess provided on front of Weight Plates. All the
recesses should be aligned and to the right as you face the weight stack.
SHROUD HOLES AND SHROUD OPTION
W. If no Optional Shroud Kit was purchased install plastic caps in all 24 shroud
holes. If installing Shrouds, fasten to Loop Upright using 11 – 3/8 x 2 ½” bolts,
19 – 3/8” flat washers and 8 – 3/8” nuts (hardware found in Shroud box). The
middle and lower bolts on the right side and the middle bolt on the left side of
