SLR Coupler

SLR Coupler

SLR left and right threaded coupler is used where none of the rebars can rotate. The internal thread of the coupler is right-handed on one side and left-handed on the other. Also, the threads created at the end of two rebars are right-handed and the other left-handed. By rotating the coupler, the threads of the two rebars are engaged with the coupler and then the threads will be closed inside the coupler until the end. This type of coupler for rebar size 16 to 50 is produced in Sahand Mechanical Connections, and it is possible to produce coupler exclusively with requested length and pitch. It is necessary to explain that the material of the couplers produced by Sahand Mechanical Connections is generally 1.1191 alloy steel. It is also possible to produce special couplers for special cases.
