Left-hande and right-handed couplers are designed to splice bars with different threads (right-handed and left-handed thread)

　　(1)Production Line:

Cutting rebar—bore—rough lathing the bottom hole—strip the ex-circle—finish turning the bottom hole--countersink—Rust-proof treatment—test and pack

　　(2)Technical data:

Material:	45 # quality carbon structural steel
Specification:	φ 14-φ 40
Application:	Used to joint ribbed rebars of HRB 335 and HRB 400 with dia from 14 mm to 40 mm. In construction laterally ,vertically and slantingly
Performance:	Reach “reinforced mechanical connection technology common point of order”JGJ 107-2004 level joint performance requirements

　　(3)Operation:
　　　　 The bars are connected initially by hand tightening and then with working and torque wrenches.

　　(4)Feature: 

① High tensile strength and precision

② Self-aligning and advanced technology provides continuity and structural integrity

③ Spliced bars as continuous lengths of reinforcing steel bars by providing full strength in tension, compression and stress reversal application

④ Quick and easy to install Fixing couplers requires no special skills or equipments. Simple mechanical ways in adopting mechanical splicing accelerates construction schedules for optimum cost and efficiency.
