Threading & Couplers

Equipped with our own in-house Lenton threading machine, we are a preferred distributor of nVent Lenton products.

Utilising this specialist machinery, we factory prepare a taper threaded rebar splicing system which compromises of a standard threaded bar end with a variety of coupler options to suit your desired applications.

Lenton A12 Couplers are designed to splice the same diameter bars where one bar is free to move and can be rotated. Quick and easy to install, they use a unique self aligning taper threaded design providing continuity and structural integrity. Develops a higher tensile strength than lap splicing.

Lenton Transitional Couplers are designed to splice different diameter bars where one bar can be rotated.

Type P13.35 Positional Couplers are designed to be used in applications when neither bar can be rotated. Having a degree of adjustability, the P13.35 Positional Coupler can also be used as a closer between two fixed bars.

Couplers, also known as mechanical splices, are used to join two or more reinforcing bars together in concrete construction.

They create a mechanical connection that allows the bars to behave like a single continuous length of rebar.

• Avoid bars protruding in casting joints
• Reduce congestion in confined spaces
• Save rebar length
• Reduce the weight of the structure
• Superior to lapped splicing in terms of load transfer

At Lemon Reinforcement, we can offer a wide range of rebar couplers with Alligator and MTB Couplers in stock for immediate dispatch. Additionally, we have our own in-house rebar threading machine which gives us maximum speed and increased flexibility to produce.

An in-situ rebar splice, requiring no bar-end preparation and providing a simple way to join two reinforcing bars.

Neither bar end preparation nor bar rotation is required with Bolted
Couplers making them a very versatile product for a wide range of on-site applications. They are ideal for new construction, repair or retrofit applications.

Featuring patented gripping technology that provides for the development of full rebar strength and improved overall structural integrity in tension, compression, stress-reversal and dynamic applications. This innovative mechanical rebar splice is designed for use in column splicing, bridge applications, piling, splicing to protruding dowels cast in concrete, closure pours, beams, chimney construction and other demanding splicing applications.

To install simply tighten the lockshear bolts where upon conical ends embed themselves into the bar. The heads then shear off the bolts when correct torque has been met, giving an instant visual check for correct installation.
