J.B engineering corporation offers bar locks & re-bar couplers which are designed to joint the reinforcement bars. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars .Jb mechanical couplers offer the solution for splicing when large diameter bars are involved. It is user friendly and cost effective. It is technically more superior. These jb bar locks & re bar couplers are user friendly and cost effective. It increases production rates because of reduced installation time and simpler quality control requirements.
These couplers comes in different type which are as follows-

Jb standard couplers These couplers are designed to join the reinforcement bars where at least one of the bars could be rotated. The threaded design of coupler helps easy engagement of the bar within the coupler with simple alignment. The standard threaded coupler comprises of internally threaded sleeve with two right handed threads tapering mid length of coupler.

The bar ends are saw cut and they are provided with threading of proprietary branded equipments and thread cutting devices. The bars are connected initially by hand tightening and then with pipe wrench [torque wrench may be preferred].

Jb transition coupler Transition couplers are designed to join different diameter bars. The tensile strength of the joints matches requirement for tensile failure of smaller diameter bar.
