available in rebar sizes #4 through #18 and exceed 135% of specified yield of
Grade 60 rebar. S/CA couplers are an approved Caltrans “Service” splice and
are recognized by ICC, ACI and most State departments of Transportation. S/CA
couplers are available in transition sizes, weldable half couplers and epoxy coated.

Barlock L-Series Couplers
Similar to the standard Coupler but is designed for use when higher loads are
required, such as extreme tension/compression application and/or seismic
loading conditions. L-Series couplers are available in rebar sizes #4 through #14
and exceed 160% of specified yield of Grade 60 rebar. L-series couplers are
approved for use by most state DOTs, are recognized as an ICC Type 2 seismic
splice, and meet ACI specifications. L-Series couplers are also available in
transition sizes, weldable half couplers and epoxy coated.
