The Dayton Superior D220XL transitional coupler is used to mechanically couple two different rebar sizes together. It consists of thick walled tubes, specially designed lock shear bolts, serrated grip rails and a weldment disc. The D220XL is made from USA melted and rolled steel.
To order specify: Finish, Bar size "A", Bar size "B" and the # of pieces
For example: "D220XL- Epoxy Coated Side A- #4 Rebar, Side B- #5 Rebar, ____ pcs
INSTALLATION
1. Insert the end of the first rebar into the coupler (for
that size rebar) until it contacts the weldment disc.
2. Holding the first rebar in place, tighten all bolts on
that half until they are hand tight against the rebar.
3. Insert the end of the second rebar into the coupler
(for that size rebar) until it contacts the weldment.
disc.
4. Holding the second rebar in place, tighten all bolts on
that half until they are hand tight against the rebar.
5. In a random, alternating pattern, tighten all bolts to
approximately 50% of the specified bolt torque value.
6. In a random, alternating pattern, tighten all bolts to
approximately 75% of the specified bolt torque value.
7. In a random, alternating pattern, tighten all bolts
until all the heads of the bolts shear off.
Note:
A. Prior to tightening, the serrated rails MUST
remain aligned in the same position as they were
manufactured. If they are damaged or knocked out
of alignment while positioning, installation MUST
cease and a new coupler used.
B. Bolt tightening MUST be done in a random
alternating pattern similar to tightening the lug nuts
on an automobile wheel.
C. A high-quality, 1? -pneumatic drive, impact
wrench with at least 100 psig air flow and 185
CFM of delivered air through a no less than 0.75?
hose MUST be used for installation.
