STEP 21: ATTACHING THE SWING BEAM MOUNT AND TRAP ARM
1: THE 4 X 4 X 47-1/2" SWING BEAM MOUNT HAS COUNTER-SUNK HOLES IN THE CENTER AND ON THE ENDS. INSTALL
THE SWING BEAM MOUNT SO THAT THE COUNTER-SUNK HOLES ON EACH END OF THE BEAM FACE OUT, AND THE
COUNTER-SUNK HOLES AT THE CENTER FACE DOWN.
2: FASTEN THE SWING BEAM MOUNT TO THE CORNER POSTS USING 3/8" X 6-1/2" CARRIAGE BOLTS WITH TORQUE
WASHERS. PLACE THE CARRIAGE BOLT INTO THE TORQUE WASHER, THEN INTO THE HOLE OF THE CORNER POST AND
SET WITH A HAMMER, USE 3/8" WASHERS AND 3/8" LOCK NUTS TO SECURE THE SWING BEAM MOUNT FROM THE
OUTSIDE. PLACE BOLT CAPS OVER THE EXPOSED THREADS AFTER SECURING.
3: THE 4 X 4 X 89-1/2" TRAP ARM WILL ATTACH TO THE UNIT IN THE SAME MANNER AS THE SWING BEAM MOUNT. THE
TRAP ARM WILL MOUNT ACROSS FROM THE SWING BEAM MOUNT ABOVE THE ROCK WALL.
