Step 5: If the coupler and/or rebar is epoxy coated, refer to “Field Touch Up Recommendations for Epoxy Coated
Couplers” Instruction Sheet PDF056. Additional copies of instructions and application information are available at
www.erico.com.
Step 4: NOTE! Ensure that the correct LENTON taper threaded rebar is utilized. Ensure dowel thread protection is removed.
Ensure that the coupler and rebar dowel threads are clean and free of rust, concrete slurry, etc (Figure 3). Clean as required
using wire brush. Install rebar dowel hand tight, approx. 4-1/2 turns clockwise. Use a pipe wrench to tighten securely (Figure 4).
Refer to Table 1 for torque required to complete installation. The LENTON brand of inspection wrench can be used by inspectors
to periodically check tightness.
Step 2: Install coupler assembly parallel
with rebar to be spliced (Figure 1).
Position nailer plate flush to form. Attach
plate using nails, etc. Complete the tying
off of the rebar. Ensure that assembly is
properly supported to prevent movement
before or during the pour. WARNING:
The nailer flange is NOT intended to
support the weight of rebar, installer or
equipment.
INSTALLATION:
Step 1: Ensure the LENTON FORM
SAVER is sized properly with project
plans. Check and ensure proper
installation of coupler thread protection
prior to mounting to formwork.
LENTON FORM SAVER assemblies are 2-piece assemblies designed for
segmental pour construction methods. The tapered threaded coupler is
factory attached to the rebar either by friction welding or a LENTON taper
threaded connection. A separate rebar (dowel) is provided with matching
external tapered threads.
LENTON FORM SAVER assemblies are shipped from regional locations
where nailer plates are installed along with temporary thread protection.
The nailer plates are factory installed to ease the installation of LENTON
FORM SAVER’S to existing concrete forms. The female coupler assembly
is also furnished with short term thread protection.
Step 3: After forms are stripped, ensure
that thread protection on couplers are
removed prior to installation of male
dowel (Figure 2).
