Rebar Couplers – Mechanical Rebar Splicing System

Code: MRS16

Rebar couplers in this mechanical splicing system join reinforcing bars in tension or compression without threading or special bar-end preparation. The coupler fits over plain or deformed bars and uses lock-shear bolts to grip the reinforcement; the bolt heads shear at the designed installation torque. The system offers a practical solution where conventional lap splicing is difficult or congested. Select the coupler size that matches the rebar diameter in the specification table.

Weldable Rebar Half Couplers

Code: WHC16

Weldable rebar half couplers, also called rebar half couplers, create a rebar connection point on structural steel members such as piles, weld plates, beams and columns. The steel connector is welded to the supporting member, after which the reinforcing bar is secured using the integrated lock-shear bolts. A 45-degree chamfer supports preparation of the welded joint. Select the coupler size for the rebar diameter and ensure the weld detail is specified and completed by suitably qualified personnel.

Threaded Rebar Couplers – Threaded Rebar Splicing System

Code: MTC16

Threaded rebar couplers mechanically connect reinforcing bars using a parallel-threaded connection. Couplers engage specially threaded bar ends and are used where designers specify mechanical splices instead of, or in addition to, lap splices. Standard sizes cover selected bar diameters from 16 mm to 40 mm as listed in the specification table. Confirm bar preparation, thread form and structural design requirements before ordering.

Rebar Pull-Out Box System

Code: POB150140

Pull-out bars are supplied in Konsa rebar pull-out boxes for planned reinforcement continuity between concrete pours in walls, stairs, slabs, balconies and other staged construction. The galvanised steel box has an interlocking lid and pre-bent Grade 500S pull-out bars. After the first pour and formwork removal, the lid is opened, the bar legs are straightened and lapped into the next reinforcement zone. Multiple bar diameters, centres, lap lengths and box widths are available, with custom and stainless-steel versions on request.
