STEP 2 - ENDCAPS ASSEMBLY
2.1 Aside from the gravity box, match up the holes on the Front Endcap Arch with the top Front Endcap
Plate holes.
2.2 Install the Nylon Strip Opposite Chute Side (OCS) using 1/4” x 5/8” bolts and 1/4” serrated flange nuts.
2.3 Insert 1/4” x 1/2” bolts in the remaining holes. Fasten with 1/4” serrated flange nuts.
2.4 Repeat Steps 2.1 - 2.3 for the back endcap arch and plate.
-NOTE: Since there is no wind lip on the back endcap, it doesnt include a Nylon Strip so only 1/4”
x 1/2” bolts should be used.
