ASSEMBLE THE T-RAIL
Tighten the Chain and Cable
Connect the 2 ends of the chain assembly together at the turnbuckle.
To connect the turnbuckle and threaded
shaft, hand tighten the turnbuckle by rotating
the turnbuckle only.
Do not rotate the threaded shaft to avoid
twisting the cable.
Twist the turnbuckle to tighten the chain tension until
the chain is 1/3" (8 mm) above the base of the T-rail.
To avoid twisting the cable, use pliers to
hold the threaded shaft while tightening
the turnbuckle with a flat screwdriver.
NOTE:
• After completing the installation, you may notice some chain drop with the door fully closed. The chain
should return to the position as shown when the door is open.
• Too much or too little tension will cause excessive noise.
