Product selection and quotation
Where is the Terminator used?
The Terminator is attached to a rebar end to provide headed anchorage in place of a hook. It helps simplify reinforcement detailing where bars are congested or hooks are difficult to arrange, such as beam-column joints.
Junsung Industry's Terminator can be assembled on site with unthreaded rebar.
| Product | Purpose | Site checks |
|---|---|---|
| Ultra Coupler | Field-assembled rebar splicing | Rebar grade, diameter and installation space |
| Terminator | Rebar end anchorage | Anchorage details and design requirements |
| PC Coupler | Rebar splicing for precast structures | Center and length tolerances and exposed rebar length |
| Structural Coupler | Splicing fixed, threaded rebars | Long/short end threads, bar spacing and assembly clearance |
Before applying the product, check the rebar grade and diameter and the site conditions. Review test documentation against the design requirements. Published test results apply to the specified specimens and sizes.
