The HT Coupler range is for the mechanical connection of deformed steel reinforcing bars complying with BS4449 grade 500B and ASTM A618 Grade 75.
The HT.LT Positional Coupler is suitable for connecting 2 bars where neither bar is rotatable, at least 1 bar is movable and extended length adjustment of the coupler is required.
Both the welded sections, female coupler and lock nut are brought together.
Spin the lock nut back up the straight thread.
Spin the female coupler up the straight 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.
Turn the female coupler off the straight thread and onto the taper thread of the male coupler and tighten with a wrench until no further movement.
Spin the lock nut from the straight thread, tighten and lock the female coupler fully.
