LENTON® LOCK S-Series Mechanical Rebar Splicing System

LENTON® LOCK S-Series Mechanical Rebar Splicing SystemPrint this page

The LENTON® LOCK S-Series, part of the LENTON LOCK Mechanical Rebar Splicing System from ERICO, provides many of the same great benefits as the LENTON LOCK B-Series, except in a smaller package. All LENTON LOCK couplers feature patented gripping technology that provides overall structural integrity in tension, compression and stress-reversal applications.

The couplers allow for easy field installation since no bar-end preparation, sawing or swaging is necessary, and they can be installed with just a standard wrench or an impact wrench, depending on coupler size. The bolt heads will shear off when proper installation tightness has been reached, which allows for complete visual inspection.  The rebar centering pin is removable which allows the coupler to fully pass onto the bar for applications such as closure pours (see PDF113 below).
 
LENTON LOCK is designed to work as a one-step transition/reducer splice.  Contact ERICO for multi-step transition capability.

Features

  • Meets or exceeds major international building code and Department of Transportation requirements
  • Uses standard rebar; requires no bar-end preparation such as sawing or swaging and is ideal for in-situ splices
  • Is smaller than other bolted splices currently available
  • Works in repair, bent bar, retrofit, precast and new construction applications
  • Installs quickly and easily using simple hand tools and does not require special skilled labor
  • Allows for simple visual inspection
  • Epoxy and mechanical galvanized coatings available in N. America
  • Product Performance

Notes:

  • Dimensions shown in chart are typical. Bolt length may vary after the bolt heads are sheared off.
  • When using air impact wrench, check the air pressure, torque rating and air flow requirements before starting installations.
  • It is recommended to use an impact wrench rated 2X the bolt torque.  Contact ERICO for additional tool recommendations.
  • Bolt heads are not required to be removed if the appropriate bolt torque is achieved.
  • Refer to complete installation instructions provided with the product or available at www.erico.com before commencing installation.
