| BRAND | | Barlock |
| DESCRIPTION | The Dayton Superior Bar-Lock Coupler System provides a simple, quick, cost effective method for splicing rebar in tension and/or compression applications. Bar-Lock couplers may be used with plain or deformed bars in sizes #4 through #18.Bar-Lock couplers utilize lock-shear bolts and special grip rails to mechanically splice with the rebar. The serrated grip rails cradle the rebar and are embedded in the rebar as the lock-shear bolts are tightened. The heads of the lock-shear bolts are designed to shear off at a prescribed torque in order to accomplish proper installation.
- Quick and easy to install –
- Saves time and money
- Eliminates bar threading and/or special bar end treatment
- No special installation equipment required.•
- High strength in tension, compression and seismic applications.•
- Available in standard, transition and weldable versions in #4 through #18 sizes.•
- Ideal for new construction and rehab projects.

| HOW TO ORDER | | Bar-Lock couplers are test-certified to exceed the requirements of, are pre-qualified and approved, or recognized by the following building approval agencies:• State Departments of Transportation• International Conference of Building Officials (ICC)• Building Officials and Code Administrators (BOCA)• Southern Building Code Congress International (SBCCI)• American Concrete Institute (ACI)• Concrete Reinforcing Steel Institute (CRSI)• City of Los Angeles Department of Building and SafetyBar-Lock coupler source material is fabricated under ISO9000 quality standards. Bar-Lock couplers are tested by independent, certified testing laboratories in four modes of testing: tension, compression, fatigue and cyclic. All tests are done to the requirements of ICC and/or Caltrans requirements utilizing ASTM A615 grade 60 rebar material. Copies of test reports are available on request. By specific name:• Bar-Lock Mechanical Coupler System manufactured by Dayton Superior Concrete Accessories.By generic description:• Mechanical butt splices utilizing lock-shear bolts and internal serrated grip rails within the coupling sleeve. They shall exceed the specification requirements for both tension and compression specified by ACI 318 and the Uniform Building code, and be recognized by the International Conference of Building Officials (ICC). |
