nVent 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 nVent LENTON taper threaded connection. A separate rebar (dowel) is provided with matching external tapered threads. nVent 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 nVent LENTON Form Savers to existing concrete forms. The female coupler assembly is also furnished with short-term thread protection.

INSTALLATION
- Step 1: Ensure the nVent LENTON Form Saver is sized properly with project plans. Check and ensure proper installation of coupler thread protection prior to mounting to formwork.
- Step 2: Install coupler assembly parallel with rebar to be spliced (Figure 1). Position the nailer plate flush to form. Attach the plate using nails, etc. Complete the tying off of the rebar. Ensure that the 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.
- Step 3: After forms are stripped, ensure that thread protection on couplers is removed prior to installation of the male dowel (Figure 2).
- Step 4: NOTE! Ensure that the correct nVent 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 the Table for torque required to complete installation if Snug Tight is not being used. The nVent LENTON brand of inspection wrench can be used by inspectors to periodically check tightness
- 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.nVent.com
