Maximum Rebar Shear
Lip Diameter (A) 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):
Tighten bolts, beginning in the center of the coupler and working
to the outside (A to C), until bolt heads shear off. A standard
wrench, impact wrench or nut runner may be utilized to tighten
the bolts.
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.

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
will be on each end of 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
