Steel Edge Nosing E2N
HD Steel Edge Nosing E2N
Stabilize construction joints for existing-to-new concrete
Additions to high-traffic industrial floor buildings and
pavements require precise load transfer, smooth
slab-to-slab transition and joint protection. All of these
requirements are met with the HD Steel Edge Nosing
– E2N assembly.
The HD E2N Nosing prevents joint spalling and
reduces repair costs in high-traffic areas, like
warehouses and loading docks. Concrete expansion
and contraction takes place as the steel bar
slides within the sleeve. The Dowel Tube allows
unrestrained movement in the horizontal direction as
the new concrete shrinks.
A complete assembly includes the HD Steel Edge
Nosing – E2N, studs, and square dowels with tube.
The hole for the Square Dowel is positioned at mid-
slab height.
The installation conforms to ACI 302.1R Guide for
Concrete Floor and Slab Construction and ACI 360
Design of Slabs-on-Ground.

18”HD Steel Edge Nosing – E2N Installation
1. Position and hold steel plate and steel bar flush with
the surface of the existing slab. Mark the locations of
the hole in the steel plate for the square dowels and
anchor bolts. Remove HD Steel Edge Nosing – E2N.
2. Drill holes 9-1/2” into slab, parallel to slab surface
using 1-1/8” drill bit for the 3/4” square dowels. Drill
holes 4-1/2” into slab, parallel to slab surface using 1/2”
drill bit. Attach joint assembly flush with existing slab
using anchor bolts.
3. Epoxy grout 3/4” x 18” square dowels with dowel
tube into pre-drilled holes so that dowel sleeve is
outside of the existing concrete surface. Dowel with
sleeve must be installed with foam on left and right
sides to allow side-to-side movement as seen in middle
picture. Once installed properly, allow epoxy to cure.
4. If the HD Steel Edge Nosing – E2N will butt up to a
sawcut contraction joint, cut through the full depth of
the side of the Steel Edge Nosing that abuts the saw-
cut to allow activation of the joint.
5. Remove the steel alignment nut from nut and bolt
alignment assembly to allow joint to activate. If steel
alignment nut is not removed the joint will not activate.
Cover the exposed steel alignment bolt with tape or
plastic sleeve so that the threads do not restrain the
new concrete slab.
6. Place and finish concrete normally. Vibration
is required to properly consolidate concrete and
eliminate air entrapment. Follow industry guidance for
consolidating concrete around embedments.
7. Concrete paste can be removed from top of HD
Steel Edge Nosing – E2N plate and bar during finishing.
8. If concrete leveling is needed, grind joint flush or
saw-cut 1/2” deep, 18 – 24 inches back into existing
slab, chip existing slab down 1/2 – 3/4” and top with
approved epoxy materials.
9. See project specifications for joint filler installation.

Ø3/8 StudE2N Square Dowel and Tube
Stabilize construction joints for existing
to new concrete floors and flatwork
Designed for joint activation and free horizontal
movement of existing-to-new concrete without
restraint.
The E2N Square Dowel and Tube has compressible
foam on both sides of the 3/4” square steel dowel
protected by a plastic tube
This allows new concrete to shrink adjacent
to existing concrete without the dowel causing
unintended damage to the concrete.
The comparison to the right shows the load transfer
on square bars compared to round bars. The load
transfer directly down into the concrete effectively
eliminates splitting stresses within the concrete.
Square bars have greater resistance to bending,
reducing edge and corner curling without increasing
the amount of steel used.E2N Square Dowel and Tube Installation Guide
1. Drill 1-1/8” hole to 9-1/2” at mid-slab depth. Space E2N Square Dowels at 18” O.C.
2. Set E2N Square Dowel and Tube in epoxy grout with Tube flush with existing slab and foam
on the left and right sides.
3. Place and finish new concrete.
