l
AASHTO and DOT
– Exceeds 125% x specified yield (f
y
) per AASHTO Standard Specifications for
Highway Bridges

(17
th
Ed). Also exceeds 135% x f
y
Grade 60 bar (81,000 psi).
l
PURPOSE

l
ACI 318 Chapter 12 FULL MECHANICAL SPLICE

– Develops in tension or compression, as
required, at least 1.25 f
y
of the bar, ASTM A 615 black deformed Grade 60.
l
COMMERCIAL APPLICATIONS
– In accordance with Building Code Requirements for Structural
Concrete, product is used in columns, beams, walls, mats, tanks, condominiums.
l
SUPERIOR TO ALL TENSION LAP SPLICES
– Strength is independent of surrounding concrete
and cover. Takes up less space than rebar lap. Replaces lap splice classes A, B or C.
l
COMPACT DESIGN
– Shorter than Type 2 series – fewer screws – less room needed – faster
installation time – ideal for hard-to-reach places.
l
FOR STANDARD REINFORCING BARS
– ASTM A 615, ASTM A 996 and equal black deformed
bars – exceeds125% x specified yield, f
y
, Grades 40, 50 and 60
.
l
CONVENIENCE
– Field installed – No specialized installation equipment – No special bar end
preparation or thread cutting – Easy visual inspection. For bars #3 – 18 (Dia.10 – 57 mm).
