MBT Rebar Couplers
The Mitro MBT Reinforcement coupler is a mechanical connector for 10 to 40mm diameter reinforcing-steel B550B. View Complete Details...
Product Specification
MBT couplers require neither bar end preparation to form threads nor bar rotation to effect installation. The bars are supported within the coupler by two serrated saddles.
MBT Series Coupler
MBT series couplers are used to connect reinforcing bars of the same diameter. They can be used when neither bar can be rotated and are available in sizes 12mm to 40mm.
No preparatory rebar work required
• No thread cutting
• No ramming
• No crimping
• No welding
Mitro MBT couplers Reinforcing provide a method of joining reinforcing bars without the need of bar end preparation such as threading. Bars are locked in place by two serrated saddles and a series of special lockshear bolts, the heads of which shear off when the predetermined tightening torque is reached, providing a visual check of correct installation. Typically used for column splicing, bridge applications, piling, beams and closure pours, Mitro MBT couplers are available in sizes to suit 10mm, 12mm, 16mm, 20mm, 25mm, 28mm, 32mm, 36mm and 40mm bar sizes.
Installation
Standard use tools are sufficient for installation. However, for efficient and easy installation, special power or electric screwdrivers can be used. You can purchase or hire specialist tools from Local Hardware.
The standard coupler consists of a seamless tube with integrated serrated runners and a set number of shear-off screws. The number of screws depends on the diameter of the rebar.
Benefits of MBT Coupler
• No preparatory work needed on the rebar ends
• Using shear-off screws means fast and safe installation
• Efficient and cost-effective installation using standard tools and with low screw shear-off moments
