LENTON® LOCK B-Series Mechanical Rebar Splicing System

Print this page

LENTON^® LOCK, an in-situ rebar splice from ERICO, requires no bar-end preparation. It is ideal for repair, new construction, or retrofit applications. The LENTON LOCK coupler features patented gripping technology that provides for the development of full rebar strength and improved overall structural integrity in tension, compression, stress-reversal and dynamic applications. This unique design allows the coupler to be smaller and more streamlined.

LENTON LOCK couplers allow for easy and simple field installation since no bar-end preparation, sawing or swaging is necessary. The couplers can be installed with just a standard wrench, nut runner or an impact wrench depending on coupler size. The bolt heads will shear off when proper installation tightness has been reached, which allows for completely visual inspection.

The completed connection performs similar to a continuous piece of rebar.

Features

Meets or exceeds major international building code and Department of Transportation requirements, including Caltrans Ultimate Splice requirement, IBC^®, UBC^® and ACI^® 318 Type 2, DIN 1045 and BS8110, BNFL, and BS5400
Uses standard rebar; requires no bar-end preparation such as sawing or swaging – ideal for in-situ splices
Is smaller than other bolted splices currently available
Performs like a continuous piece of rebar
Works in repair, bent bar, retrofit, precast and new construction applications
Provides superior fatigue performance
Works with a variety of standard US and international rebar grades
Installs quickly and easily using simple hand tools – does not require special skilled labor
Allows for simple visual inspection
Splices will do a one-step transition to the next smallest size (e.g. LL28B1 will connnect 25 mm rebar to 28 mm rebar)

NOTES

Works as a one-step transition.
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 reccommended to use an impact wrench rated 2X the bolt torque.
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.
