LENTON® Bolt Couplers

S4, S5 Series

LENTON taper threaded couplers can be
assembled with a standard pipe wrench.
The LENTON inspection wrench, available
from ERICO, may be used to periodically
check tightness (see chart below).
Proper LENTON inspection wrench settings
should be used for the given bar sizes.

Installation:

Step 1

- Remove the bar end protectors, if present, from
the ends of the taper threaded rebar. Visually inspect the
threads to ensure that they are free of concrete, rust or
other debris and are not damaged.
Use a wire brush if threads need to be cleaned.

Step 2

- Inspect part number on the coupler to ensure it is

the proper size for the bar being spliced. (See chart below)

Step 3

- If present, remove cap or internal coupler protector
from the coupler. Visually inspect internal thread to ensure
it is free of concrete or other debris.

Step 4

- Refer to Step 1 above for bar cleanliness. Place
the taper end of the coupler onto the taper threaded bar
and rotate the coupler clockwise until hand tight,
(approx. 4-1/2 turns). If using a standard pipe wrench,
rotate the coupler clockwise to securely tighten the coupler.
The LENTON inspection wrench can be used by an
inspector to periodically check tightness (see chart below
for wrench setting).

* The integrity, torque, and proper installation criteria of the straight threaded connection should be evaluated by a qualified engineer.
