#40 Zinc Two-Piece Expansion Joint
Two-piece Zinc expansion joint

Zinc Expansion Joint #40 is a two-piece, slip joint that finishes butt ends of adjacent
panels in wide or tall walls and ceilings to allow for multi-directional movement.
Panels are attached to parallel studs through the expansion joint flanges, enabling the
finished surface to expand or contract naturally without cracking. #40 is ideal for joining
dissimilar wall types such as wood framing to CMU and at construction joints.
Adjustable expansion opening or reveal is 1/4" to 5/8". Additional weather shields should
be installed behind the joint to enhance the weather resistance of this system.

1-3/8" J-Weep Low-Back
Used as a plaster or casing stop bead with stucco and E.I.F.S. Systems

1-3/8" J-Weep Low-Back (2 inch back flange) is commonly used as a plaster stop at the
top of doors and windows over traditional head flashings. J-Weep Low-Back is nail,
screw or staple-attached to the frame or sheathing, then foam insulation, cement board
or metal lath can be installed over it. In any case, the protruding ridge of the metal must
extend beyond the plane of overlaid materials to serve as a ground for the stucco or
E.I.F.S. application. Installed in conjunction with 1" rigid insulation associated with
one-coat plaster stucco systems, the 1-3/8" ground provides proper depth for plaster
keying. Galvanized for corrosion protection, it also is available with weep holes.

1-3/8" J-Weep with a 2" nailing flange should not be used as a foundation weep screed
for three-coat stucco applications. This casing or plaster stop bead should only be used
on approved one-coat systems.

The International Building Code (IBC)* requires that all weep screeds have a 3-1/2"
nailing flange, weep holes and a minimum thickness of 26-gauge steel. This product
does not conform to code-required work if used as a foundation weep.

•Provides straight-edge stops for applied plaster stucco and E.I.F.S.
•Offers exacting grounds and protective weeps.
•Resists corrosion.


3-1/2" J-Weep High-Back
Used as sill weep screed or at door and window opening

J-Weep High-Back Plaster Stop is a J-shaped square nosed trim manufactured from
26-gauge galvanized steel. The 1-3/8" ground is designed for use with 1" of foam, lath
and a one coat 3/8" proprietary stucco system. The foam will be placed over the drainage
holes to allow drainage and the high backed rear flange serves as the rear flashing which
is covered by the building paper to encourage drainage.

J-Weep High-Back Plaster Stop is provided in other grounds including, 3/8", 1/2", 3/4"
and 7/8" grounds for proprietary one coat and multi coat stucco systems with ES reports
that require this type of drainage mechanism to meet the requirements of those systems.

All of the products described in this section are not intended and should not be used in
lieu of a foundation weep screed as described in ASTM C1063 for three coat stucco
applications. These products should only be used with proprietary stucco systems.

•Provides straight-edge stops for applied plaster stucco and E.I.F.S.
•Offers exacting grounds and protective weeps
•Resists corrosion
