FORM SAVER
LENTON FORM SAVER is ideal for segmental pours because it eliminates protruding dowels. It is uniquely
designed with LENTON taper threads, factory-installed thread protectors and keyed mounting holes for easy
attachment to the form.

LENTON and CADWELD products can be used with all grades of rebar. 1
The CADWELD
®
Advantage
How It Works
CADWELD filler material is placed in a graphite
crucible and ignited, causing an exothermic reaction
to take place, turning it into molten filler metal.
By melting through a steel disk at the bottom of the
crucible, the filler metal flows out of the crucible along
a channel in the graphite pouring basin directing the
flow into the CADWELD splice sleeve. (The CADWELD
splice sleeve is located approximately equidistant over
the rebar ends to be spliced.) CADWELD filler metal
mechanically locks or keys the splice sleeve to the
reinforcing bars using the bar deformations and
internal grooves in the splice sleeve. The finished
connection develops strength and consistency
unequalled in the industry.
When the reinforcing bars are in tension, the
CADWELD filler metal is in shear and transfers the
load from the deformations on one bar to the
internally grooved splice sleeve to the deformations
on the other bar.
When the reinforcing bars are in compression, the
load is transferred through the layer of CADWELD
filler material that fills the space between the ends of
the bars.
For splicing reinforcing bars the CADWELD rebar
splicing system creates a mechanical connection that
interlocks the rebars together. It is not a weld.
CADWELD
®
has earned its reputation as the strongest splice for
the most demanding applications. The primary use for CADWELD
is in critical structures requiring high safety margins such as blast-
resistant facilities, pressure-vessel applications or seismic design. Due
to its popularity in critical structures, CADWELD is the worlds most
tested mechanical splice. Its record includes more than 25,000 actual
field-made tensile tests. Key features of the product include:
Consistently developing minimum ultimate strength of the rebar
(>150% of yield)
Excellent joining of circumferential bars
Simplifying acceleration of splicing schedules
Retrofitting and repairing with short dowels and no bar-end
preparation
Complies with ASME
®
Section III Div. 2 (ACI
®
359) and ACI 349
Utilized in more than 200 nuclear projects worldwide, and all
103 operating reactors in the USA.

Mechanical Rebar Splicing
The CADWELD
®
Rebar Splice is a mechanical means (not a
weldment) of splicing deformed bars that produces a joint
with basically the same mechanical properties as those of
Advantages:
1.
Does not require special bar-end preparation. Works with flame, shear or
saw-cut bar ends.
2.
Works on all grades of steel even with bars where the chemistry of the
steel (known or unknown) rules out field welding. Can be used to splice
thread deformed and all thread bars.
3.
No specific preheat temperature or controlled cooling is required even with
alloy or high carbon bars.
4.
Splices can be made regardless of the ambient temperature of the bars.
5. Can be visually inspected does not require radiography.
(X-rays are not necessary.)
6.
CADWELD splices are designed to meet or exceed all ACI
®
318, 349 and 359
Building Code requirements and ASME
®
Section III Division 2.
7.
No special skill is required on the part of the user.
8. Placing schedules can be accelerated because of the ease and speed of
splicing. (It is ideal for slip forming.)
9.
Splicing equipment can be designed to meet special space and working
restrictions.
10. Complies with requirements of NQA-1 & NCA 3800.

Splicing to Short Rebar Dowels
CADWELD
®
Rebar Splices can be made on short rebar
dowels using either the standard end alignment fitting or
the end packing cap. The line drawings below indicate the
use of the end packing caps on short dowels in both the
vertical and horizontal position.
This feature permits varying lengths of dowels to suit job

working convenience. However, the dowel height may
be as short as 3 to 5 inches (76 to 127 mm) to facilitate
