nVent LENTON mechanical splices reduce congestion, and are ideal for fast and easy rebar placing when using sliding or climbing formwork.

Purpose & Performance

nVent LENTON Mechanical Splices, are a taper-threaded splicing system that assures a positive locking connection, providing continuity and structural integrity to reinforced concrete construction. nVent LENTON spliced bars behave as continuous lengths of reinforcing steel bars by providing “full strength” in tension, compression and stress reversal applications.

The nVent LENTON self-aligning, taper-threaded design provides ease of installation, consistent performance and durability. It also develops higher tensile strength than lap splicing and provides full load transfer with the slimmest and shortest coupler possible.

nVent LENTON Standard Couplers are designed to splice the same diameter bars where at least one bar is free to be rotated and is not restricted in its axial direction. The couplers are machined to have taper threads at both ends, creating a mechanical butt splice of two sections of reinforcing steel.

Features

• Designed to splice the same diameter bars where the second bar can be rotated and is not restricted in its axial direction
• Slim design maintains concrete cover
• Installs quickly and easily

nVent LENTON Interlok was engineered for use in precast construction. It is designed to provide structural integrity between load bearing precast concrete elements such as columns, beams, shear walls, and panels. nVent LENTON Interlok provides superior dynamic, seismic and ultimate strength performance for moment frame applications.

Typical applications include column to column, column to foundation, shearwall to foundation, shearwall to shearwall, panel to panel, wall to floor slab and architectural panels.

Features

• Maintains structural integrity between precast sections.
• Provides load path continuity – reinforcing steel bars (rebar) act as one continuous bar.
• Tensile loads are transferred through the reinforcing bar independent of the compressive strength of the concrete.
• Helps eliminate costly and unsightly patchwork.
• Designed to meet or exceed building code requirements.
• Easy to use.

The nVent LENTON Terminator provides an alternative to hooked rebar, or an anchor or stop nut for rebar passing through a pile plank or structural steel element. The front face of the coupler is generously designed to carry the full tension load of the rebar when the anchor is bearing against concrete or structural steel.
