1 Description of the Dyna-Glide™Climbing Protection Systems
MSA Dyna-Glide™ Climbing Protection Systems are used to prevent and/or arrest falls from heights and
facilitate the climber’s performance of work. The systems are used for mounting to already-installed
ladders, to corners of lattice towers, and to other suitably strong structures which must be climbed.
This manual deals only with systems, which are center-mounted to the rungs of vertical fixed ladders. This
is the most prevalent type of system. However, by substitution of different mounting assemblies, DynaGlide systems may be attached to almost any structure that is permissible to climb. Systems may also be
constructed to continuously protect the climber when traveling horizontally, and around curves, corners
and obstacles in the climb path.
A properly installed, used and maintained Dyna-Glide system will help to stabilize a climber at a work
position, will permit restricted travel of the climber along the rail, and will automatically stop an accidental
fall within inches. The Dyna-Glide system may be used by more than one person at a time.
A complete system consists of:
a) standard joinable straight rail sections of length 7 feet 4-3/16 inches (2240 mm);
b) if needed, custom (built to special specification) curved rail sections of the concave, convex or
compound type;
c) Standard rail connector assemblies used to couple rail sections together;
d) Standard mounting assemblies for attachment of rail sections to fixed ladders and other structures;
e) If needed, custom (built to special specification) mounting assemblies for attachment of rail sections
to structural members of unusual configuration;
f) A Dyna-Glide fall arrester which engages the rail sections, permits the climber to work position,
permits travel along the rail, and stops against a rail notch in case the climber falls;
g) End stops to prevent the fall arrester from slipping out of the bottom or top end of a string of rail
sections;
h) A full body harness; and
i) If needed, a variety of accessories which enhance mobility and provide continuous protection, conve-
nience and comfort.

1.1 Rail Sections
The rail sections are made of either hot galvanized steel or stainless steel. They have a C-profile cross
section with rectangular cut outs (slots) at 5.51 inch (140 mm) intervals for coupling adjacent rail sections
together and for connection of the rail sections to mounting assemblies. Notches are located at 5.51 inch
(140 mm) intervals to serve as stops for the fall arrester. The standard length of a rail section is 7 feet 4-3/
16 inches (2240 mm) See Figure 1.

3 Notch
Rail sections may be curved to go around objects in the climb path or to bridge between two straight runs
of rail that form an angle with each other. Curved rail sections may have concave, convex or compound
curvature.
1.2 Rail Connector Assemblies
Rail connectors are used to fasten the rail sections together. These units may be made of stainless steel or
hot galvanized steel. One rail connector assembly is required to fasten together one pair of adjacent rail
sections. The assembly consists of a connector plate and two each bolts, nuts, and lock washers. See
Figure 2. During the installation of the rail system it is critically important that the butt joint between
adjacent rail sections is very tight and secured by the rail connector assembly. In case an interference
occurs between the connector plate bolt and a ladder rung (as shown in Figure 3, Rail connector
assembly), then a special rail connector assembly (P/N 506329) is used. This special assembly has a
longer connector plate (P/N 621496) which allows shifting the bolt locations to eliminate the interference.
See Figure 3, Special rail connector assembly and Figure 4.

1.3 Mounting Assemblies
A variety of standard mounting assemblies are available to attach rail sections to the structure which is to
be climbed. In general, all mounting assemblies have a bracket that is shaped and sized to mate with
certain common structural members. The mounting interface with the rail section is always a standard bolt
connection. However, structural members can take on a variety of shapes, sizes and orientations.
Therefore, a variety of mounting brackets is necessary. Custom mounting assemblies may be ordered built
to special specification. At least two mounting assemblies are always required for each rail section and
these must be spaced apart by no more that 66.14 inches (1680 mm) Although this manual deals only with
rung mounting of rails to fixed ladders, several types of mounting assemblies are described below in order
for the user to plan for future installations.

1.3.1 Rung Mounting Assemblies
Fixed ladders are the most common of all structures to which rail systems are mounted. Fixed ladders are
rigidly anchored to other structures. The ladder normally has rungs with diameter up to 1 1/4 inches (32 mm)
and width between side rails of 12-18 inches (305 mm - 457 mm)
To comply with USA Federal OSHA requirements, rungs must be a minimum of 16 inches wide. The DynaGlide rail sections are normally mounted in the center of the rungs - provided this leaves enough space on
each side to easily place the foot on the rungs even when winter work boots are being worn. The DynaGlide rail is 1.96 inches (50 mm) wide. Assuming a winter boot width to be 5 inches, the rung width must be
at least 14 inches.
Rungs are usually of circular cross-section, although some are angle, rectangular bar or channel. The
standard rung mounting assembly is suitable for rungs of circular cross-section and right angle. The main
part of the standard assembly is an alligator clamp (rung mounting assembly) which is bolted to the rail with
two each bolts, nuts and lock washers as shown in Figure 5.
For instances in which the ladder rung is less than 14 inches in width, the standoff rung mounting assembly
can be used to improve climbing ease. This assembly provides means for attachment of the rail section to
the ladder rungs while spacing the rail section 2.25 inches (57.2 mm), forward of the rungs thereby providing
a wider space for the foot. See Figure 6.

For installation using standoff rung mounting brackets, one base support bracket must be mounted at the
beginning of each vertical run of rail to add additional stiffness. See Figure 7.
