BT parallel threaded couplers are suited to projects which require high volumes of couplers.
They produce a full strength joint and yet are one of the smallest couplers in the Ancon range. The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bar.
BT Type A
The Type A coupler is used for applications where the continuation bar can be rotated. The ends of the bars are upset and threaded for half the length of the coupler.
BT Type B
The Type B coupler uses the same coupler as the Type A system, but one bar is threaded for the full coupler length. It is designed for applications where it is difficult but not impossible to rotate the continuation bar.
BT Type C
The Type C coupler has an additional locknut and is used where the continuation bar cannot be rotated. The continuation bar is threaded for the full length of the coupler plus the length of the locknut.
BT couplers are also available to join bars of different diameters. Contact Ancon for details.
