CRSI Splicing Bar

Bars to be spliced are inserted equal distances into the sleeve. Bars may be shear-cut, flame-cut, or saw-cut, however, a bar-end check is recommended. Bars of different sizes can be spliced with this system. This mechanical splice can also be used for joining reinforcing bars to structural steel members.
