Product Description

The advantage of Bar lock coupler:
Quick and easy to install,Bar Lock requires no special installation equipment. The high strength couplers are
excellent for new concrete construction or rehab projects. The Bar Lock rebar coupler system provides a cost
effective method for splicing smooth or deformed rebar in tension and/or compression applications.

Connection way of Bar Lock coupler:
JBCZ Bar Lock Coupler System provides a simple, quick, cost effective method for splicing smooth or deformed rebar in tension and/ or compression applications. Bar Lock couplers are effective when used as a "positional" coupler when the rebar is fixed in place or when the rebar is free to rotate. Bar Lock couplers utilize lock shear
bolts and serrated grip rails to mechanically splice the rebar. 

This type of mechanical splice consists of a coupling sleeve with shearhead screws which are designed to shear off at a specified torque. The reinforcing bars are inserted to meet at a stop in the center of the coupling sleeve and the screws are tightened. The tightening process embeds the pointed screws into the bars. For one type splice, the screws force the bars into contact with internal gripping rails. For the other type of splice, the screws force the bars to wedge into the coupling sleeve's converging interior wall. The heads of the screws shear off at a prescribed tightening torque. The screws can be tightened using a standard socket wrench or pneumatic impact wrench. For making a splice between two fixed bars, coupling sleeves without a center stop are available. This sleeve can be slipped completely onto one bar and subsequently repositioned over teh two bar ends
