The HT Coupler range is for the mechanical connection of deformed steel reinforcing bars complying with The California Departmentof Transportation (Caltrans) authorization testing.
The HT.LT Positional Coupler is suitable for connecting two bars where neither bar is rotatable, at least one bar is movable and extended length adjustment of the coupler is required.
Both male threads of the HT.LT Coupler joint are always delivered to site welded to the appropriate re-bar.
The joint should always be tightened by the use of a wrench, until there is no further movement available between the two sections.
NO TORQUE WRENCH REQUIRED

Both the male sections, female coupler and lock nut are brought together.
Spin the lock nut and the female coupler up the longer parallel thread. Then bring the tapered male thread close to the female coupler, so as the gap between the two components is less than the maximum extension limit (Refer to table).
Spin the female coupler off the parallel thread and onto the taper thread of the male coupler and tighten with a wrench until no further movement.
Spin the lock nut off the parallel thread, tighten and lock the female coupler fully.
