B. Install Tensioning Terminal
1. Install the Adjust-A-Body®with Hanger Bolt by driving the hanger bolt / lag end into the pre-drilled hole
in your end post using a 5/32" hex wrench in the hex-broached end of the hanger bolt (if applicable) or a
1/4" wrench on the wrench flat between the machine threads and the wood lag (if no broach).
3. Slide the body of the Adjust-a-Body®with Extended Length Hanger Bolt Tensioner onto the bare end of the cable,
threaded end first, and pull it the length of the cable until it is stopped by the ferrule already swaged onto the cable.
2. Screw the lock nut all the way onto the 2"-long threaded end of the bolt.
Note: turn counter-clockwise to tighten/tension/close.
4. Thread the body (with the cable attached) onto the Hanger Bolt and turn 8 turns onto the male threads.
C. Feed Cable through Intermediate Posts
1. Feed the bare end of the cable through all intermediate posts and to the end post where you will be installing the
Push-Lock®fitting.

D. Feed/Crimp Cable through Corner Posts
As composite sleeves can be somewhat fragile, it is recommended to stop and start at corners.
Do not allow a cable to exit a post on an angle; it can damage the sleeve.
3. At opposite end post with tensioning terminal, detach the body from the Hanger Bolt to allow cable
slack so you can perform the next step.
4. Back at post with swageless terminal, push the cable into the hole in the fitting as far as it will go
(approximately 1-1/16"). Twist the cable in a clockwise direction as you push it into the fitting.
E. Install Swageless Terminal
1. Place lag thread into the pre-drilled hole and drive lag thread into wood post using our DRIVER PL-LAG tool (or 3/8"
open-end wrench) on wrench flats milled into body of fitting. Stop turning when shoulder on fitting between lag thread
and body makes contact with wood post.
2. Pull the cable tightly along the side of the fitting and mark the cable at the end of the fitting.
Cut the cable 1-3/16" beyond that mark.
5. Return to the post with tensioning terminal and hand turn the body back onto the Hanger Bolt as far as possible.
Note: If you have trouble inserting the cable into the fitting, it may be because the locking wedges have become stuck. This is not a
defect! Here’s what you can do to “free the wedges” — For Pull-Lock®or Push-Lock®fittings for 1/8” cable, using either a RFXPL-KEY
or 1/4” diameter bolt, insert the RFXPL-KEY or bolt into the hole and press until the wedges move freely. Perform the same operation
for a 3/16” Pull-Lock®or Push-Lock®, except use a 16d nail or another tool with 1/8” or smaller diameter. Anything larger than what is
recommended can actually get stuck inside the fitting – NOT what you want!

F. Tension Cables
1. Tension the cable by holding it with cable gripping pliers or the RFX Small Cable Gripper and vice grips to prevent the
cable from turning while you turn the Adjust-A-Body®with a 7/16" open-end wrench. Be careful to protect the cable from
damage while tensioning the Adjust-A-Body®.
2. Tension all cables to desired amount in sequence, beginning with the
center cables, moving up and down toward the top and bottom. As you
tension each cable, give it a sharp pull downward mid-span to help set
the wedges, then re-tension as necessary in the same sequence.
Be aware that the cable may move as much as 3/16" toward the
tensioning terminal as the wedges seat.
3. While holding the body still with a 7/16" open-end wrench, turn the lock nut against the body and tighten with a wrench,
leaving approximately 1/2" of thread visible for future tensioning.
RailFX Small Cable Gripper
As an alternative to a large cable
gripper, this small gripper will clamp
on the cable while tensioning to keep
the cable from unraveling.
