and untrained personnel, especially children, away from the equipment.
The Hog Leg® Wall Brace System is designed to brace a masonry wall built in accordance with the Standard
Practice for Bracing Masonry Walls Under Construction. A minimum of two (2) braces per wall panel are required,
located 20% of wall length from each end of the panel. Wall panels are to be a maximum of 25’-0” long. Bracing
requirements differ for reinforced and unreinforced walls, as well as the amount of reinforcement installed in each
wall. Bracing requirements also differ based upon current and predicted maximum wind speeds until final
structural connections are in place. Note that the information shown in this manual is designed to support
reinforced masonry walls during the intermediate period of construction. For information on bracing
unreinforced walls or for criteria for the initial period of construction, refer to the latest edition of Standard Practice
for Bracing Masonry Walls Under Construction or contact a licensed Professional Engineer familiar with local and
national codes.
The Hog Leg® Wall Brace is to be installed by trained employees under the supervision of a competent person.
All parts should be inspected before installation; any worn, damaged, or corroded parts should be taken out of
service immediately and replaced.
Do not alter any part of the Hog Leg®.
Warning: This manual should be used as a reference for bracing, but not for final design. Before attempting to
brace any wall, consult the latest edition of Standard Practice for Bracing Masonry Walls Under Construction,
OSHA, or a local licensed Professional Engineer.
Warning: Minimum of 10” of overlap required on Hog Leg® Extension connection.
Warning: Restricted Access Zones must be established during the construction of masonry walls, as well as after
wall bracing has been installed. These zones must be maintained by all trades until permanent supporting ele-
ments of the structure are in place. All employees working around masonry walls during construction must be aware
of the evacuation wind speeds to know when to evacuate these zones. These wind speeds are described in The
Standard Practice for Bracing Masonry Walls Under Construction.
EZG Manufacturing strongly recommends grouting in 4’ to 6’ lifts as the walls are being laid. Low lift grouting as
the walls are being laid allows for fewer braces and an overall stronger intermediate structure as described in the
Standard Practice for Bracing Masonry Walls Under Construction.
The data in this manual applies to the Hog Leg® Wall Brace only. Wall strength between connections, floor
anchoring, deadman sizing, and site conditions are the responsibility of the Contractor. EZG Manufacturing
strongly encourages the use of embedded deadmen as these are less suseptable to adverse and varying site
conditions.
The data within this manual was developed with the aid of professional engineers and is specifically developed for
use with the Hog Leg system. For more information on the engineering firm used to help create this guide,
please see the final page of this manual. EZG Manufacturing makes no implications for use with other systems
and complies with the Standard Practice for Bracing Masonry Walls Under Construction under reference to
Sections 1.5 (page 12) and C1.5 (page 29).

Installation of a Hog Leg®
The Hog Leg® Wall Brace System is designed to be
constructed in sections starting from the Wall Bracket and
working down to the floor anchor. Install each Hog Leg®
Extension individually. Do not put Hog Leg® Extensions
together before installing to Wall or Floor Bracket.
Wall Bracket Installation (Detail A): The Hog Leg® Wall
Connection Bracket is designed to be placed as the wall is
constructed.
The following illustration is a guideline for installation of
the Hog Leg® Wall Brace.
1) Determine the required bracing as defined by national
and local codes. If not familiar with these codes consult a
licensed Professional Engineer in your area to interpret the
bracing standards and recommend a bracing plan.
2) As the masonry wall is being laid, install the Backing
Plate (HL-5) against wall and slide T-bar (HL-6) through the
backing plate and the head joint of the block. Then slide the
Wall Bracket (HL-24) over the T-bar on the other side as
shown in Detail A. Drive the Wedge (HL-7) through the T-
bar until it tightens the Backing Plate and Wall Bracket
against the sides of the wall. Install the Latch Pin (09-407)
through the Wedge as close to the T-bar as possible.
Wall Bracket Installation (Detail A Optional): Though it is
recommended for ease of installation to use the Hog Leg®
T-Bar and Wedge to install the Wall Bracket to the wall, a
¾” All Thread Rod can be used if desired.
1) Determine the required bracing as defined by national
and local codes. If not familiar with these codes consult a
licensed Professional Engineer in your area to interpret the
bracing standards and recommend a bracing plan.
2) As the masonry wall is being laid, notch the corner of the
block were the brace is to be installed to allow clearance to
slide the All Thread Rod through.
3) Install the Backing Plate (HL-5) against wall and slide the
All Thread Rod (Customer Supplied) through the backing
plate and the notched head joint of the block. Then slide
the Wall Bracket (HL-24) over the All Thread Rod on the
other side as shown in Detail A (Optional). Tighten nuts
on both sides of the wall. Nuts should be tightened until
the Wall Bracket and the Backing Plate are snug against
the wall.
Extension Installation: Foreaseofinstallation, install Hog
Leg® Extension to Wall Bracket. Then add Hog Leg®
Extensions until reaching proper anchor location.
1) Align the holes in the end of the Hog Leg® Extension
with the holes in the Wall Bracket and use the Hitch Pin (09-
403) and Safety Clip (09-400) to attach as shown in Detail A.

2) Make sure you alternate starting with a Small Hog Leg®
Extension (2-3/8” OD) or a Large Hog Leg® Extension
(2-7/8” OD) at every other brace. This will keep the amount of
Extensions used equal, maximizing the amount of braces you
will get from each Hog Leg® Wall Brace Kit.
3) Continue adding Hog Leg® Extensions as shown in Detail B
until the desired length is obtained. To locate where to pour
the deadman for the base of the Hog Leg®, take the height
of the brace installation and multiply by 0.75. Example:
Brace Height of 16 feet x 0.75 = Brace Run of 12 feet from
the wall.
CAUTION: Keep installation as close to the design
guidelines shown in this manual as possible. If the brace
is installed at a steeper angle or beyond 90° perpendicular
to the wall, the holding power of the brace will be
reduced.
4) Secure the Floor Bracket with anchors that meet all
applicable standards and regulations as shown in Detail C.
Kicker Installation: For extreme wind speeds (greater th 40
MPH) or requirements that exceed Standard Practice for
Bracing Masonry Walls Under Construction a kicker is
required , on brace lengths 22’-11” or longer. For Brace
Lengths longer than 26’-3” a Kicker is required for all
circumstances. For extreme wind speeds (greater than 40
MPH) or requirements that exceed Standard Practice for
Bracing Masonry Walls Under Construction a Kicker and
Guide Wires are required, on brace lengths 26’-3”. For Brace
Lengths longer than 30’-5” a Kicker and Guide Wires are
required for all circumstances. The Kicker should be installed
at the midpoint of the Hog Leg® Wall Brace. The Kicker
then extends downward at a 90° angle from the Hog Leg®
Wall Brace and mounts to the wall. To determine wall height
to install kicker, refer to page 10 of this manual. For Guide
Wire installation, refer to page 11 of this manual.
1) Install the Kicker Adjustment Pipe to the Hog Leg® by
inserting the Hitch Pin through the Hog Leg® Extension
and insert Safety Clip as shown in Detail D.
2) Add Hog Leg® Extensions as required to reach the
Wall Bracket.
Removal of Hog Leg® Bracing
To comply with Standard Practice for Bracing Masonry
Walls Under Construction, the Hog Leg® Bracing System
must not be removed until the wall is permanently supported.
You may refer to this standard in Chapter 3 Section 3.5 of
the Standard Practice for Bracing Masonry Walls Under
Construction manual.
