LENTON® Transition Couplers

LENTON® Transition CouplersPrint this page

LENTON® Transition couplers are designed to splice different diameter bars where one bar can be rotated.

Features

  • Unique self-aligning taper-threaded design provides continuity and structural integrity
  • Spliced bars behave as continuous lengths of reinforcing steel bars by providing full strength in tension, compression and stress reversal applications
  • Designed to withstand man-made blasts, and other seismic events
  • Quick and easy to install
  • Develops higher tensile strength than lap splicing
  • Provides full load transfer with the slimmest and shortest coupler possible
  • Product Performance – LENTON standard couplers are designed to meet or exceed:

    For applications where the coupler must be cast into an element for later continuation of the reinforcing bar, ERICO supplies a range of accessories to assist the user. In addition to the plastic caps supplied with the couplers, steel screw-in caps are available to seal the coupler end where the greater protection is required and polycarbonate cap plugs are available for use with Form-Fixer plates where a degree of tensile load must be restrained by the cap-plug.
