Type A System
1 ] Screw the coupler to the rear of the thread on the fixed bar and lock tight. The bar end should be central within the coupler.
2 ] Remove the plastic cap from the coupler. Position and rotate the continuation bar in the coupler.
3 ] Tighten the joint using a wrench on the continuation bar. After tightening there should be no more than 2-4mm of thread exposed, depending on the diameter of the rebar.
Type B System
1 ] Screw the coupler to the rear of the thread on the continuation bar.
2 ] Position the continuation bar with the coupler against the end of the first bar.
3 ] Rotate the coupler from the continuation bar to engage against the rear of the thread on the opposing bar and lock tight.
4 ] Using a wrench, rotate the continuation bar to lock the two bar ends against each other within the coupler. After tightening, the length of exposed thread should be no more than half of the coupler length plus 2-4mm depending on the diameter of the rebar.
Type C System
1 ] Screw the coupler to the rear of the thread on the continuation bar.
2 ] Position the continuation bar with the coupler against the end of the first bar.
3 ] Rotate the coupler from the continuation bar to engage against the rear of the thread on the opposing bar and lock tight.
Type D System
1 ] Run the locknut onto the fixed bar.
2 ] Run the second locknut followed by the coupler to the end of the thread on the continuation bar.
3 ] Position the continuation bar with the coupler against the end of the fixed bar.
4 ] Run the coupler from the continuation bar onto the fixed bar.
5 ] Rotate the locknut along the continuation bar to abut the coupler.
6 ] Tighten the locknuts against each other using a pair of wrenches.
