Instructions For Horizontal Splicing
1. Clean rebar ends as per “Rebar Cleaning Procedure” on
page 2.
2. Slide splice sleeve over bar before placing rebar into
position for splicing.
The average gap between bar ends should not exceed
1/4-in. (6mm). If a natural gap is not provided by the
shape of the reinforcing bar ends, a spacer can be used.
The spacer is not required to remain in position.
Spacers are enclosed in an envelope in each carton of
CADWELD
® filler material. For certain conditions, a
spacer may be omitted. Contact ERICO ® for additional
information.
3. Position splice sleeve by placing tap hole directly in line
with the gap between the bar ends.
Lift the splice sleeve completely and drive down the
vent pins. The splice sleeve need not be concentric with
the rebar.
For sleeves without vent pins, please see page 8.
4. Place a double wrap of packing material around rebar,
against both ends of sleeve. The second wrap of packing
should be placed alongside the first. DO NOT force
packing into splice sleeve.
5. Place end alignment fitting around rebar. Lock and slide
into position against packing and sleeve. Be sure that
the fittings slide over the ends of the sleeve.
6. Place horizontal packing clamp in position. (Normally it
will hang from the rebar.) Draw bar must not block
access to the sleeve tap hole.
Tighten hand knob on end of clamp to draw end
alignment fittings firmly into position over sleeve ends.
This action wedges the packing against the sleeve and
rebar to prevent leakage of filler material.
7. Position ceramic insert guide tube assembly firmly into
tap hole, making sure it is completely seated in the tap
hole.
8. Flame dry pouring basin and crucible before using.
As a check, a drop of water should boil off rapidly.
9. Place pouring basin into position on the sleeve.
Place chain around sleeve and finger tighten thumb
nut. Do not over tighten thumb nut.
