Structural Coupler
HOME > >
Features
- Structural coupler for connecting threaded rebar.
- Connects rebar in vertical, horizontal, diagonal and other directions.
- Resists compression, shear and bending stresses as well as tensile stress.
- Can be installed even when both rebars to be connected are fixed.
- Absorbs center and length tolerances of rebars fixed at both ends.
- Shortens construction time through immediate structural connection.
- Made to order.

Components
Bolt Coupler
Nut Coupler
T-Sleeve
Installation Steps
1.Thread the two rebar ends with long and short threads, then insert the bolt coupler and nut coupler.
(The bolt and nut couplers may be inserted onto either the long- or short-threaded rebar.)
2. Thread the T-sleeve onto the threaded portions of both rebars.
3. Position the structure so the rebar spacing and centerlines match the dimensions specified in the table.
4.Loosen and tighten the installed T-sleeve until the members meet, then adjust the overall structure for vertical and horizontal alignment. Ensure no gap remains at the contact surfaces.
5. Thread the bolt coupler and nut coupler together to complete the connection.
