nVent LENTON Interlok Form Saver Seal
nVent LENTON Interlok Form Saver Seal
The nVent LENTON Interlok Form Saver Seal provides an easy and efficient means for securing nVent LENTON Interlok Grout-Fill Coupler variants to formwork. Designed for cast-in-place applications, simply click and tap the Form Saver Seal into the coupler and utilize the sturdy mounting plate to fasten onto the formwork. The integrated seal allows the secondary rebar to be inserted into the coupler and prevents concrete paste contamination and grout leakage out of the cavity.
Interlok Grout-Fill Coupler variants can be used to splice steel bars in various cast-in-place applications. When combined with the Form Saver Seal, this powerful combination can be utilized for segmental pours, closure pours, post-tensioned slabs, and repair work.
