2. Lengthened connection

Couplers are fully screwed in the lengthened thread of a rebar in advance, then reverse screwed in the end thread of the rebar that is being connected. To lock the coupler, just twist the rebar for half to one turn. Standard couplersare optional.

3. Locknut-added connection

Designed for situations that rebars can't rotate, such as hooked rebars and dockings of bridges, place piles reinforcement cages. Lock the coupler by screwing the locks and rebars in the lengthend thread in advance, then screw in the thread of another rebar's end and lock the coupler with the locknut. Standard and flare couplers with locknuts are optional.

4. Double-sided thread connection

Designed for situations that rebars can't rotate but internal forces of the rebars are adjustable, such as construction joints and post cast strips. The coupler is equipped with double-sided threads, which is able to release and tighten two rebars in one direction.
