Ancon MBT Transition Series Coupler

Features:

• The MBT Transition series of couplers is used to connect reinforcing bars of different diameters.

• Couplers are easy to install and achieve failure loads higher than 115% of the characteristic yield strength of grade 500 reinforcing bar.

• Neither bar end preparation to form threads or bar rotation are required.

• The bar ends are supported within the coupler by two serrated saddles, and as the lock-shear bolts are tightened, the conical ends embed themselves into the bar. As this happens the serrated saddles bite into both the bar and the shell of the coupler.

• The lock-shear bolts of couplers up to and including the ET20 can be tightened using a ratchet wrench. For larger couplers a nut runner is recommended.

• In all cases heavy duty sockets should be used.

• When the pre-determined tightening torque for the bolts is reached, the heads shear off leaving the top of the installed bolt slightly proud of the coupler. This provides an instant visual check of correct installation.

• MBT couplers can also be used to join imperial, plain round or deformed reinforcing bars.

Performance:

• MBT couplers are designed and manufactured in accordance with BS EN ISO 9001.
