Figure 3 Solid contact between bar and stop pin as shown.
Step 3
: Insert rebar into LENTON LOCK coupler until contact
is made with the center stop pin as shown in Figure 3. Rebar
must be flush against center stop pin.
Step 4 for coupler sizes 12(#4) – 36(#11):
For rebar sizes 40 through 57(#18), follow ‘Alternate step 4’ on
the next page.
For Caltrans Ultimate performance on sizes 32(#10) and 36(#11),
also follow ‘Alternate step 4’ on the next page.
To avoid bolts from vibrating loose, it is suggested that each bolt
be pre-torqued (Approximately <50% is recommended torque)
prior to applying final bolt torque.
Tighten bolts, beginning in the center of the coupler and working
to the outside (A to D). A standard wrench, impact wrench or nut
runner may be utilized to tighten the bolts.

Step 1:
Read all instructions and procedures before
commencing splicing. Ensure the LENTON
®
LOCK coupler is
sized properly for the bars being spliced and per project plans.
Product should arrive with bolts configured as shown in Figure 1.
One round point bolt should be on each end for sizes 10 (#3)
through 40mm. Two round point bolts should be on each end for
sizes 43 (#14) and 57 (#18).
Step 2:
Ensure the rebar is free of any excessive dirt, concrete
slurry, rust, etc. which may affect product performance. Ensure
maximum rebar lip does not exceed limits set in Figure 2.
Excessive shear lip interferes with rebar installation.
*When using an air impact wrench it is recommended to use a wrench with double the torque rating identified. Impact sockets should always be used when using an
impact wrench. Additionally, check the air pressure and air flow requirements prior to installation. Refer to complete installation instructions provided with the product or
available at
rior to commencing installation.
