1.6 Coupler Installation Procedures at Precasting Plant
A. Attaching Coupler To Rebar:
1. Remove the thread protector. Examine threaded bar end to make sure it is undamaged and clean.
If cleaning is required, a wire brush should be used.
2. Determine whether the coupler is the correct size for the bars being spliced. Each coupler is identified with the bar
size and the part number (see chart). Remove the internal thread protector if installed.
3. Install the coupler by rotating by hand until tight - approximately 4 turns (Right Hand Thread).
4. While holding the bar stationary, rotate the coupler with a standard 18” pipe wrench until the connection is fully
tightened (see figure).
Comment on Tightness:
Proper tightness may be checked by the installer using a LENTON ® brand of inspection wrench. Refer to chart for inspection
wrench settings.
NOTE: The inspection wrench will emit a “click” that can be felt as well as heard when the inspection wrench
setting noted in the chart has been reached.
B. Attach The Coupler To The Form:
Follow the instructions provided with the Form Mounting Fixture. It is important that the Form Mounting Fixture is tightened
sufficiently so that the urethane grommet is fully expanded thereby preventing cement from entering the coupler .
