8 EXPERIENCE INNOVATION QUALITY Components for Macalloy 460, S460 and 520 Bar Systems. Standard Components Macalloy offers a range of standard components, including forks, spades, pins, couplers and turnbuckles. These components are designed and tested to exceed the tensile capacity of the bar, which itself is based upon the cross sectional area of the thread form. The design and geometric dimensions are the same for all the systems, enabling the designer to go from one system to another, without making any design changes. Forks are designed to be connected to a BS EN 10025 grade S355 plate...

Establish the thread size of the tendon together with its orientation i.e. left hand or right hand. Note all left hand bars are marked with paint. 2. Screw a lock cover onto the threaded end of the bar with the taper pointing along the bar. Screw the lock cover all the way along the thread length. 3. Screw the fork onto the threaded end of the bar for a distance approximately...
